Bolingbrook – November 01, 2026 -- Pain deep in the buttock that runs down the back of the leg does not always point to a herniated disc. A small hip muscle called the piriformis can irritate the sciatic nerve and produce similar symptoms, according to a HelloNation article featuring Dr. Mitch Quill, D.C., a chiropractor in Bolingbrook, Illinois.
The piriformis sits right next to the sciatic nerve
The piriformis is a small muscle deep in the hip that helps rotate the hip and stabilize the pelvis during movement. The sciatic nerve passes close to it. When the muscle becomes tight, inflamed, or irritated, it can press on the nerve and cause pain, tingling, or numbness.
Piriformis syndrome often starts as a deep buttock ache. Pain may travel down the back of the thigh and sometimes reaches the calf.
Sitting, stairs, and hip rotation can aggravate piriformis pain
Prolonged sitting, climbing stairs, or rotating the hip may make piriformis symptoms worse, and the buttock may be tender. A herniated disc more often causes low back pain alongside leg symptoms, while piriformis syndrome generally involves more buttock pain and less back pain. The article stresses that the symptoms overlap.
No single test confirms piriformis syndrome
An evaluation may include symptom history, hip movement, strength, and reflex testing. Imaging generally helps rule out disc problems or other spinal conditions rather than directly confirming piriformis syndrome.
Conservative care starts with gentle stretching
The article outlines adjusting activities that worsen symptoms, gentle stretching, strengthening surrounding muscles, and improving sitting habits. Stretches should feel gentle and should never cause sharp pain. Chiropractic care, physical therapy, and massage may be part of an individualized plan.
The article advises prompt medical care for severe pain, leg weakness, or loss of bladder or bowel control.
