I had this monster for 14-1/2 years. I sat on a donut. Then, my neurologist prescribed an off-label anti-seizure medication for a daily persistent headache. Within 2 weeks, my butt was better. It was Topamax. My pelvic physical therapist mentioned that she had heard of this. Sooooo, why did she not mention this to me? See what your doctor says. Worth a shot, right? Good luck.
