Sciatica is widely known — it produces intense, radiating pain along the sciatic nerve from the lower back into the buttock and leg. Lesser known is that roughly 5% of sciatica cases stem from piriformis syndrome.
The piriformis muscle connects the lowest vertebrae to the upper leg, but it passes through the same pelvic opening as the sciatic nerve — the "sciatic notch" — placing them in very close proximity.
Physical therapy offers a noninvasive solution for piriformis pain syndrome, whether stemming from muscle issues or nerve irritation.
Recognizing Piriformis Pain Syndrome
Piriformis syndrome is often confused with hip bursitis or a herniated disc due to similar symptoms.
Common signs include:
- Numbness or tingling in the buttocks radiating into the leg
- Difficulty sitting or bearing weight on the affected buttock
- Muscle tenderness or spasming in the buttock
- Buttock or leg pain worsening with sitting or activity
- Buttock muscle pain during rectal exam
- Sciatica-like symptoms with outward hip movement/rotation, especially against resistance
Causes aren't fully understood but often involve injury, overuse, irritation, or structural abnormalities like scoliosis. Diagnosis is typically based on symptoms and physical exam.
Physical Therapy and Piriformis Syndrome
The piriformis is used daily, and physical therapy generally provides the most effective long-term relief — focusing on stretches and exercises to improve flexibility and strength.
One example exercise:
- Lie flat on your back with both knees bent
- Cross your left ankle over your right knee
- Gently pull your right knee toward your chest
- Hold for five deep breaths, then slowly return to start
Additional physical therapy approaches may include:
- Osteopathic manipulation for bone and tissue alignment
- Hot and cold therapy to reduce spasming and inflammation
- Transcutaneous electrical nerve stimulation or ultrasound to disrupt pain signals
For intense symptoms, medications (pain relievers, anti-inflammatories, muscle relaxants) or targeted muscle injections may be added. Personalized prevention recommendations can help maintain piriformis health long-term.
