I have been suffering from piriformis syndrome for at least 3 years now. I have tried injections, ultra sound, PT, medication, and stretching. Nothing has worked. My pain is most severe when sitting. I have read about a new kind of MRI developed by Dr. Aaron Filler called MR neurography. This allows the Dr. to actually see the nerves. I am planning on calling to schedule an appointment for this soon and was wondering if anyone else out there has tried it.
