Leg pain can be a mild discomfort or a severe, debilitating condition that interferes with daily activities. It may stem from injuries, nerve issues, or underlying medical conditions. Understanding the possible causes can help you seek the right treatment. Here are nine common conditions that could be responsible for your leg pain.

1. Peripheral Artery Disease (PAD)

PAD occurs when narrowed arteries reduce blood flow to the legs, leading to cramping, pain, or weakness, especially while walking. This condition is linked to atherosclerosis (plaque buildup in arteries) and can increase the risk of serious cardiovascular issues.

2. Sciatica

Sciatica is caused by compression or irritation of the sciatic nerve, which runs from the lower back down to the legs. It often results in shooting pain, tingling, or numbness along one side of the leg. Herniated discs or spinal stenosis are common triggers.

3. Deep Vein Thrombosis (DVT)

DVT occurs when a blood clot forms in a deep vein, usually in the legs. Symptoms include swelling, warmth, and tenderness. If left untreated, the clot can travel to the lungs, leading to a life-threatening pulmonary embolism.

4. Arthritis

Osteoarthritis and rheumatoid arthritis can cause joint pain, stiffness, and swelling in the knees, hips, and ankles. Arthritis-related leg pain often worsens with movement and may lead to reduced mobility over time.

5. Muscle Cramps

Sudden, involuntary muscle contractions can lead to intense leg pain, often occurring at night. Dehydration, electrolyte imbalances, and overuse of muscles are common causes. Stretching and staying hydrated can help prevent cramps.

6. Neuropathy

Peripheral neuropathy results from nerve damage, often due to diabetes, infections, or injuries. It causes burning pain, tingling, and weakness in the legs, and symptoms may worsen over time if left untreated.

7. Shin Splints

Shin splints are a common cause of pain along the shinbone, often affecting runners and athletes. Repetitive stress on the lower leg muscles leads to inflammation and discomfort, especially after exercise.

8. Tendonitis

Tendonitis occurs when tendons in the legs become inflamed due to repetitive movements or strain. Common types include Achilles tendonitis (back of the heel) and patellar tendonitis (knee pain), which can make walking or climbing stairs painful.

9. Spinal Stenosis

Narrowing of the spinal canal can put pressure on the nerves leading to the legs, causing pain, numbness, and weakness. Symptoms often worsen when standing or walking for extended periods.

When to See a Doctor
