Piriformis Syndrome

WHAT is

Piriformis Syndrome

Piriformis syndrome is a condition in which the piriformis muscle, located in the buttocks, irritates or compresses the sciatic nerve. This can cause pain, numbness, or tingling in the buttocks that may radiate down the back of the leg. Symptoms often worsen with activities such as sitting for long periods, walking, running, or climbing stairs.

Common Causes

  • Muscle Tightness or Spasm: Overuse or strain of the piriformis muscle
  • Prolonged Sitting: Putting pressure on the buttocks and sciatic nerve
  • Injury or Trauma: Falls or direct impact to the hip or buttock
  • Anatomical Variations: In some people, the sciatic nerve passes through or near the piriformis muscle, increasing risk

SYMPTOMS

Symptoms to Watch For

  • Pain, burning, or tenderness in the buttocks
  • Numbness or tingling radiating down the thigh, calf, or foot
  • Increased discomfort with sitting, walking, running, or climbing stairs
  • Persistent or chronic discomfort if left untreated

Diagnosis

How It’s Diagnosed

Doctors diagnose piriformis syndrome primarily through a physical exam that assesses muscle tenderness, flexibility, and nerve irritation. Imaging tests such as MRI or CT scans may be used to rule out other causes of sciatica, such as herniated discs or spinal stenosis.

Treatment Options

Non‑surgical / Lifestyle Approaches:

  • Gentle stretching and strengthening exercises
  • Rest and activity modification to reduce pressure on the nerve
  • Heat or ice therapy for pain relief
  • Massage therapy or myofascial release
  • Over-the-counter pain relievers or anti-inflammatories

Advanced Treatments:

  • Corticosteroid injections to reduce inflammation and nerve irritation
  • In rare cases, surgery to relieve pressure on the sciatic nerve
