Piriformis Syndrome

The piriformis muscle becomes excessively tight, spasmodic, or inflamed, compressing or irritating the sciatic nerve that passes beneath it, resulting in localized pain and radiating symptoms along the sciatic nerve distribution.
Causes
Prolonged sitting, crossing legs, or habitual one-sided weight-bearing
Repetitive hip external rotation activities such as running or hiking
Gluteal muscle imbalance (weak gluteus medius leading to overcompensation by the piriformis)
Anterior pelvic tilt or leg length discrepancy
Direct trauma to the buttocks or post-injection scarring
Symptoms
Deep aching or stabbing pain in the buttocks, which may radiate to the back of the thigh, calf, or even the sole of the foot
Pain intensifies after prolonged sitting or when rising from a seated position
Pain triggered by hip external rotation or passive internal rotation
In severe cases, numbness, weakness in the lower limbs, resembling sciatic nerve pain
Treatment
Interferential therapy + heat application: Relaxes the piriformis muscle and reduces nerve sensitivity
Ultrasound + deep tissue massage: Releases myofascial restrictions
Shockwave therapy: Targets chronic trigger points
Exercise therapy: Piriformis stretching + gluteus medius strengthening + neural gliding exercises, assisting pelvic stability and reducing excessive piriformis contraction
Acupuncture + dry needling: Directly addresses piriformis trigger points
Potential consequences of not treating early
Chronic nerve sensitization, expanding the pain area
Prolonged sciatic nerve compression → Decreased sensation and strength in the lower limbs
Development of refractory buttock and lower limb pain syndrome
