Is periforme muscle spasam after childbirth treatable? Have had pain 4 nearly 5 years now with no help. Relief only from nsaids. Tx

Yes. Piriformis syndrome can be due to nerve root irritation associated with the sciatic nerve. If physical therapy modalities do not help, then the cause needs to be diagnosed and treated. Possible causes include lumbar radiculopathy, hip issues, sacroiliac joint dysfunction, or variant anatomy of how the sciatic nerve runs around/through the pyriformis.
Yes. Piriformis muscles are deep in the pelvis and when overly contracted can put pressure on the sciatic nerve. There are physical therapists trained specifically on the pelvic floor muscles who can help as well as osteopathic physicians that should be able to help you get this muscle back to normal.
