Pain that originates from muscles and/or joints of the pelvis or hip can travel down into the leg and may also affect the foot. The hip joint, sacroiliac joint, and the piriformis muscle are common structures that may cause leg pain. Pain from these structures can mimic radiculopathy or nerve pain.1
Wear-and-tear of the hip joint (osteoarthritis) commonly causes:
- Deep aching pain in the hip and groin region that radiates to the front of the thigh and the knee, sometimes including areas below the knee2,3
- Locking, sticking, or grinding sound (also called crepitus) that occurs during hip movements4
The pain is usually worse in the morning, after prolonged sitting or resting, or after performing physical activities.

Sacroiliac (SI) joint dysfunction
- Pain that originates in the lower back and buttock area and is referred to the back and side of the thigh.
- Effect of posture, such as standing from a seated position and/or sitting on a hard surface typically increases the pain.
SI joint pain may be relieved while lying down or walking.
- Shooting, burning pain that travels down the back of the leg
- Tingling the back of the leg
- Numbness in the buttock and hip
Piriformis syndrome pain may increase or flare-up while getting out of bed or while sitting for prolonged periods of time.
Leg pain can also occur due to a variety of other factors, such as pulled muscle issues, trauma, aging, strain, dehydration, or from being sedentary with minimal hip and leg movements. An accurate diagnosis of the underlying cause can help formulate an effective treatment for the specific condition.
