I am sorry to hear that you are having such a terrible time!
If you don't mind me asking, what does the pain feel like? You had mentioned in a response to one of my posts that you had an allergic reaction to a recent ESI. Is it possible that this pain is related in any way to that?
As far as suggestions, I have recently discoverd Tiger Balm..not sure if it is similar to the ointment that you are using, but it has sometimes worked for me on pain when all else fails. It's cheap as well. We also had a discussion about sleep...not sure if you saw my last reply, but Trazadone really works for me, without anything much in the way of side effects and I am sensitive to side effects. I take a low dose - 50mg - at bedtime. Might be something to talk to your dr about?
I really hope that you can find some relief soon!
