I dont know if it helps, but I've suffered chronic pelvic pain for many years, and for the last couple the hospital pain management team have given me pain injections and the difference has been amazing - halved my pain for about 8 months. I have heard that they work reasonably well too for arthritic types of pain too. I also use a tens machine and when I go to sleep I warm up wheat packs which help sooth enough to fall asleep.

I wish you all the best with it, its rotten living with pain every day, really does get depressing..
