Piriformis syndrome is a condition that arises from the contraction or spasm of a hip muscle called the piriformis. During this contraction, the sciatic nerve, one of the nerves around the piriformis muscle, can become compressed or irritated. As a result, the compressed sciatic nerve may lead to symptoms such as pain, numbness, and tingling radiating from the hip to the leg, mimicking the pain associated with lumbar disc herniation, especially when standing for extended periods.

Treatment typically involves rest, physical therapy, stretching exercises, trigger point injections, and pain relievers.
