Leg Pain: Symptoms, Causes, Types, Diagnosis & Treatments

Team AckoJan 20, 2025

Leg Pain (LP) is one of the common health concerns that people tend to ignore for a long time. Often, after a long day of work or following any exertion, having LP is normal. However, if you have it even at rest or after walking short distances, it could spell danger. Musculoskeletal causes are the most common reason for this condition at present. This has been attributed to poor lifestyle choices and sedentary work. Here’s an overview of this condition.

Types of Leg Pain

The leg has many components, such as bones, ligaments, tendons, blood vessels, nerves, etc. All of these structures, when affected, can result in pain. Only after a careful history and examination is it possible to narrow down the cause of Leg Pain. Here are some types of LP.

1. Musculoskeletal pain

Musculoskeletal pain is the most common cause of leg pain, resulting from damage to muscles, tendons, ligaments, or bones. It can be triggered by injuries such as sprains, fractures, or overuse, with pain often intensifying during movement. In severe cases, fractures may cause excruciating pain, preventing weight-bearing on the affected leg.

2. Neuropathic pain

Neuropathic pain arises from nerve damage and is often experienced as a sharp or burning sensation. It can occur even when the leg is at rest, frequently accompanied by tingling, numbness, or a "pins-and-needles" feeling. Conditions like sciatica or diabetic neuropathy are common causes of this type of pain.

3. Vascular pain

Typically triggered by physical activity, vascular pain is linked to issues with blood vessels, like atherosclerosis or varicose veins. It often worsens with movement and improves with rest. Other symptoms include skin discolouration or temperature changes, and in severe cases, ulcers may form.

Symptoms & Causes of Leg Pain

As mentioned, there are multiple structures in the leg that can be damaged, resulting in pain. Each of them has some associated features that can give a hint towards the final diagnosis. The most common causes are as follows.

1. Muscle Strain

A muscle strain occurs when muscle fibres are overstretched or torn due to excessive force or sudden movements. Common causes of muscle strain in the legs include improper warm-up, overexertion during exercise, or lifting heavy objects. Muscle strains can happen in various parts of the leg, such as the hamstrings, quadriceps, or calves.

Depending on the severity, the injury can be classified as mild, moderate, or severe. Mild strains involve minor muscle fibres being stretched, while severe strains may involve complete tears in the muscle fibres. Recovery time depends on the severity and the location of the strain.

Symptoms:

Sudden sharp pain during activity, especially when the muscle is stretched or contracted
Muscle weakness, making it difficult to move the affected leg properly
Swelling or bruising around the injury site
Muscle spasms or tightness in the affected area
Pain that intensifies with movement or exertion

2. Sciatica

Sciatica is a condition that arises when the sciatic nerve, the longest nerve in the body, becomes compressed or irritated. This often occurs due to a herniated disc, bone spurs, or inflammation in the spine, which places pressure on the nerve. The pain typically radiates along the path of the sciatic nerve, from the lower back, through the hips, and down one leg.

Sciatica can range from mild to severe and may be accompanied by other symptoms, such as tingling, numbness, or weakness in the leg or foot. It is often aggravated by sitting, standing for long periods, or sudden movements.

Symptoms:

Sharp, shooting pain that radiates from the lower back down one leg, typically on one side of the body
Numbness or tingling sensations in the leg or foot
Weakness in the affected leg, making it difficult to walk or stand
Pain that worsens when sitting or standing for extended periods
Difficulty moving or controlling the affected leg due to muscle weakness

3. Peripheral Artery Disease (PAD)

Peripheral Artery Disease (PAD) is a condition caused by the narrowing or blockage of blood vessels in the legs due to the accumulation of fatty deposits, primarily cholesterol and other lipids. These deposits, known as plaque, reduce blood flow to the lower extremities, leading to various symptoms.

PAD is most common among older adults and those with underlying conditions like diabetes, hypertension, or high cholesterol. The reduced blood flow can result in leg pain, especially during physical activity, and may be relieved by rest. In severe cases, PAD can lead to ulcers, gangrene, or the need for amputation if not properly managed.

Symptoms:

Leg pain while walking, also called intermittent claudication, which usually stops with rest.
Coldness or numbness in the leg or foot, particularly after physical activity
Changes in skin color, with the leg or foot appearing pale or bluish
Slow-healing wounds or ulcers on the feet or legs
Decreased hair growth or thickening of the toenails

4. Deep Vein Thrombosis (DVT)

Deep Vein Thrombosis (DVT) refers to the formation of a blood clot in one of the deep veins of the leg, most commonly in the calf or thigh. It is typically caused by prolonged immobility, such as long flights, bed rest, or after surgery, which can lead to blood stagnation and clotting.

In addition, conditions like obesity, smoking, or a family history of blood clotting disorders may increase the risk. If the clot is displaced and travels to the lungs, it can cause a life-threatening condition called pulmonary embolism. Symptoms of DVT can sometimes be subtle, but the condition requires prompt treatment to prevent complications.

Symptoms:

Swelling in one leg, especially in the calf or ankle
Red or discolored skin, which may feel warm to the touch
Pain or tenderness in the affected leg, particularly when standing or walking
A feeling of heaviness or tightness in the leg
In severe cases, shortness of breath or chest pain (indicating a pulmonary embolism)

5. Tendonitis

Tendonitis is the inflammation or irritation of a tendon, which connects muscles to bones. It is most commonly caused by repetitive motions or overuse, making athletes and individuals with certain occupations more susceptible. In the legs, tendonitis often affects the Achilles tendon (at the back of the ankle), the patellar tendon (at the knee), or the hamstring tendons.

Overuse without proper rest can lead to small tears in the tendon fibres, causing inflammation, pain, and swelling. If untreated, tendonitis can lead to chronic discomfort or further injury.

Symptoms:

Pain or tenderness over the affected tendon, which increases when touched or pressed
Swelling around the tendon or joint
Pain that worsens with activity or specific movements, such as running or jumping
Limited range of motion due to pain or tightness
Warmth or redness around the tendon, indicating inflammation

6. Osteoarthritis

Osteoarthritis (OA) is a degenerative joint disease that affects the cartilage, which acts as a cushion between bones. In OA, the cartilage wears down over time, causing pain, swelling, and stiffness. This condition typically affects the weight-bearing joints such as the knees, hips, and lower back, though it can also affect the ankles and toes.

Risk factors for OA include ageing, previous joint injuries, obesity, and genetic predisposition. OA leads to joint dysfunction and reduced mobility as the cartilage continues to degrade and bones rub against each other.

Symptoms:

Joint pain that worsens with movement or activity, and may improve with rest
Stiffness, particularly after long periods of inactivity or in the morning
Swelling in the affected joint, which may feel warm to the touch
Limited range of motion or difficulty bending or straightening the affected joint
A feeling of grating or popping during movement

7. Shin Splints

Shin splints, also known as medial tibial stress syndrome, are overuse injuries that cause pain along the inner part of the shinbone (tibia). It typically results from repetitive activities like running, especially on hard surfaces or with improper footwear. Athletes, especially runners, dancers, and military personnel, are at higher risk.

This condition occurs when the muscles and tendons surrounding the shinbone become irritated or inflamed due to overuse or sudden changes in activity level. With proper rest and treatment, shin splints can be managed, but recurrence is common if the underlying causes are not addressed.

Symptoms:

Dull, aching pain along the front or inner part of the shin
Pain that worsens with exercise, particularly running or jumping
Swelling or tenderness along the shinbone
Pain that subsides with rest but returns with activity
In severe cases, more intense pain that persists even after stopping physical activity

8. Cramps

Cramps are usually the result of muscle fatigue or dehydration. It feels like a sudden sharp pain along with tightening of the muscles of the calf. Most of us have experienced a leg cramp after long periods of exercise or keeping the leg in one position for a prolonged period of time.

Cramps can occur at night, particularly in the calves, and can be caused by an imbalance of electrolytes, such as potassium, magnesium, or calcium. Certain medical conditions and medications can also contribute to cramps.

Symptoms:

Sudden sharp pain along the calf or thigh
Muscle tightening or knotting during the cramp
Difficulty moving or stretching the affected leg during the cramp
Pain may persist for a few seconds to several minutes
Cramping episodes that are more frequent during physical activity or at night

9. Bone or Soft Tissue Injury

The leg has many muscles, ligaments, and tendons, any one of which can be damaged because of increased stress or strain. The tendons near the heel can get inflamed resulting in a painful condition known as tendinitis. Muscle groups such as the hamstrings and quadriceps can also get injured because of overstretching. Shin splints are another common cause of leg pain resulting in pain and swelling along the shin bone. It has been linked with orthopaedic problems such as flat feet.

Symptoms:

Immediate pain following injury, especially after physical activity or trauma
Swelling and tenderness at the injury site
Bruising or discoloration around the injury
Limited range of motion in the affected leg
Difficulty putting weight on the affected leg

10. Vascular Disorders

Medical conditions that affect the blood vessels of the leg are often painful. One of the most common conditions is atherosclerosis, which is the narrowing or hardening of arteries due to the build-up of fatty deposits. In severe cases, the oxygen supply to the legs can be compromised, leading to severe pain.

Another vascular condition, varicose veins, involves swollen and twisted veins that often appear bluish on the calf. Deep vein thrombosis (DVT), a clotting disorder, is another common vascular cause that can lead to serious complications.

Symptoms:

Pain or heaviness in the leg, particularly after prolonged standing
Swelling, especially around the veins in the leg
Varicose veins that are visible and can feel lumpy or tender to

Diagnosis of Leg pain

Physical Examination:

Examine the leg for swelling, deformities, or changes in skin colour. Gently palpate to assess heat or changes in pulse, which may indicate circulation problems. Check leg movement, pain levels, and reflexes, and test for numbness or muscle weakness. Observe the patient's walking pattern for signs of mobility issues.

Medical History:

Note the pain's duration, type (sharp, dull, burning), and frequency. Ask about previous injuries, chronic conditions (e.g., arthritis, diabetes), and physical activities. Inquire about current medications (e.g., blood thinners, pain relievers) and past treatments (e.g., physical therapy, surgery).

Medical Imaging:

X-ray: Detects fractures, arthritis, or structural issues.
MRI: Identifies soft tissue damage or joint/spinal problems.
CT Scan: Highlights fractures, tumours, or nerve damage.
Ultrasound: Identifies blood clots, muscle, or tendon injuries.
Bone Scan: Detects bone infections or early arthritis.
Arteriography: Reveals blocked arteries (e.g., peripheral artery disease).
EMG: Diagnoses nerve or muscle damage.

Nerve Blocks:

Epidural Steroid: Diagnoses sciatica.
Facet Joint: Identifies lower back pain.
Sacroiliac Joint: Detects pelvic or hip pain.
Sciatic Nerve Block: Confirms sciatic nerve involvement.

When to See a Doctor?

Mild cases of Leg Pain can be easily managed at home. However, if you have LP that is constant and prolonged, not responding to painkillers, it may be time for a visit to the doctor.

Other reasons to visit a doctor for Leg Pain include:

The leg feels cool to the touch or looks pale compared to normal skin
There is accompanying swelling
The pain increases even while resting
The skin over the leg looks red or flushed and feels warm
The pain is so severe that you are unable to walk at all or support your body weight on your leg.

Treatment for Leg Pain

The treatment for leg pain varies depending on the underlying cause, but it generally focuses on reducing inflammation, relieving pain, and promoting healing. Here are based on common medical practices and recommendations for managing leg pain caused by various conditions:

For Cramps and Muscle Strain

Muscle cramps and strains are typically caused by muscle fatigue, dehydration, or overuse. The treatments for both focus on reducing inflammation, improving circulation, and relieving pain.

1. Cramps:

Stretching: Gently stretching the muscle during or after the cramp can help alleviate pain and reduce the intensity.
Hydration: Ensuring adequate water intake to prevent dehydration, which can contribute to cramping.
Heat or Cold Therapy: Applying a warm compress or heating pad can help relax the muscles, while ice packs can reduce inflammation if there is swelling.
Over-the-counter Pain Relievers: Medications such as ibuprofen or acetaminophen can help relieve discomfort.

2. Muscle Strain:

Rest: Avoiding activities that strain the affected muscle is essential for recovery.
Cold Therapy: Applying an ice pack to the injured area within the first 48 hours helps reduce swelling and inflammation.
Compression: Using an elastic bandage to wrap the strained area can help control swelling.
Elevation: Elevating the affected leg above heart level helps reduce swelling and pain.
Rehabilitation: Once the pain subsides, stretching and strengthening exercises under the guidance of a healthcare professional are essential for complete recovery.

For Tendinitis (Including Shin Splints)

Tendinitis, including shin splints, occurs when tendons or muscles in the leg become inflamed due to overuse or improper activity. Treatment typically focuses on rest and reducing inflammation.

1. Tendinitis:

Rest: Allowing the tendon to heal by avoiding activities that aggravate the pain.
Ice Therapy: Applying ice to the affected area for 20 minutes at a time helps reduce inflammation.
NSAIDs (Non-Steroidal Anti-Inflammatory Drugs): Medications like ibuprofen or naproxen can reduce pain and inflammation.
Physical Therapy: Stretching and strengthening exercises help rehabilitate the affected muscle or tendon.
Supportive Footwear: Wearing shoes with proper arch support and cushioning can alleviate pressure on the tendons.

2. Shin Splints:

Rest and Ice: Similar to tendinitis, resting and icing the affected area helps manage pain and inflammation.
Foot Orthotics: Using custom-made insoles can address any underlying structural issues, such as flat feet, which may be contributing to the shin splints.
Stretching: Regular calf and hamstring stretches can reduce tension on the shin and lower leg.
Low-Impact Activities: Engaging in activities like swimming or cycling, which put less strain on the shins, can aid in recovery.

For Vascular Disorders (Atherosclerosis, Varicose Veins, Deep Vein Thrombosis)

Vascular disorders affect the blood vessels in the legs, often causing pain and discomfort. Treatment varies depending on the severity and the specific condition.

1. Atherosclerosis:

Lifestyle Modifications: Adopting a heart-healthy diet (low in saturated fats, high in fibre), regular physical activity, and smoking cessation can help prevent further progression.
Medications: Statins, antiplatelet drugs (like aspirin), or blood pressure medications may be prescribed to manage cholesterol levels, reduce blood clots, and improve circulation.
Surgical Intervention: In severe cases, procedures like angioplasty (opening narrowed arteries) or bypass surgery may be necessary to improve blood flow to the legs.

2. Varicose Veins:

Compression Stockings: Wearing compression stockings helps improve blood flow in the legs, reducing swelling and discomfort associated with varicose veins.
Sclerotherapy: A procedure where a solution is injected into the veins to cause them to collapse and eventually be absorbed by the body.
Laser Therapy: Laser treatment can be used to seal off smaller varicose veins, reducing pain and improving appearance.
Surgical Treatment: In more severe cases, vein stripping or other surgical techniques may be used to remove or close off damaged veins.

3. Deep Vein Thrombosis (DVT):

Anticoagulants (Blood Thinners): Medications like heparin or warfarin are commonly prescribed to prevent blood clots from growing or travelling to the lungs (pulmonary embolism).
Compression Stockings: These help prevent swelling and reduce the risk of developing further blood clots.
Elevating the Leg: Elevating the affected leg can help reduce swelling and improve circulation.
Thrombectomy: In severe cases, surgical removal of the clot may be necessary.

For Sciatica and Nerve-related Pain

Sciatica and other nerve-related pain can arise from compression or irritation of nerves in the spine, often due to a herniated disc or other spinal issues.

1. Sciatica:

Physical Therapy: Exercises to strengthen the back and core muscles, improve flexibility, and reduce nerve compression.
Medications: Non-steroidal anti-inflammatory drugs (NSAIDs) like ibuprofen to reduce inflammation, or oral steroids for short-term relief.
Heat and Cold Therapy: Ice packs can reduce inflammation, while heating pads help relax muscles and alleviate discomfort.
Epidural Steroid Injections: In cases of severe pain, an injection of corticosteroids near the affected nerve can help reduce inflammation and provide relief.

2. Nerve Pain:

Pain Medications: In addition to NSAIDs, medications like gabapentin or pregabalin may be used to manage nerve pain.
Physical Therapy: Targeted exercises to strengthen muscles and reduce pressure on nerves.
Spinal Manipulation or Chiropractic Care: In some cases, manual therapies like chiropractic adjustments can provide relief by realigning the spine.

For Bone and Soft Tissue Injuries

Injuries to the bones, ligaments, and soft tissues in the legs are common causes of leg pain. The treatment for these injuries often involves addressing inflammation, pain, and restoring mobility.

1. Bone Injuries (Fractures and Stress Fractures):

Rest and Immobilisation: A cast, splint, or brace is often used to immobilise the bone and allow it to heal.
Surgical Intervention: In cases of severe fractures, surgery may be required to realign the bones or insert screws or plates to stabilise the area.
Rehabilitation: Physical therapy to restore strength, flexibility, and mobility after the bone has healed.

2. Soft Tissue Injuries (Sprains, Ligament Tears):

Rest and Ice: Resting the injured area and applying ice to reduce swelling and pain.
Compression and Elevation: Wrapping the injured area with an elastic bandage to prevent swelling and elevating the leg.
Physical Therapy: Stretching and strengthening exercises are essential in regaining function and preventing future injuries.

Tips to Avoid Leg Pain

To avoid leg pain and promote long-term health, focusing on strengthening muscles and maintaining a healthy lifestyle is essential. The bones and muscles of the legs and back play a significant role in supporting the body’s weight, so ensuring they are in optimal condition is key. Here's how you can approach it:

Exercise regularly: Aim for at least 5 days of physical activity each week. Incorporate a balance of cardiovascular exercise, strength training, and stretching or yoga to build muscle strength and improve flexibility.
Warm-up and cool down: Always warm up before and cool down after exercising. This reduces muscle strain and minimises the risk of injury.
Follow a balanced diet: Eat a diet rich in protein, fruits, and vegetables to help support muscle repair and overall health. A well-rounded diet also helps in maintaining a healthy weight.
Maintain a healthy weight: Keeping your weight within a healthy range can relieve pressure on your legs and joints, thus reducing the risk of pain and discomfort.
Limit smoking and alcohol: Reducing or eliminating smoking and limiting alcohol intake supports better circulation and overall well-being, contributing to pain prevention.
