I can't think of too much other than what you have mentioned.

Have you tried a lidocaine cream (can't remember if you have one or not)? It doesn't help me a lot but when things are pretty bad it can help take the edge off in areas like my hands where it's hard to put a patch. And I think we all understand that sometimes even a little relief can make the difference between something being tolerable or not.

Someone also mentioned in another thread about acupuncture. I haven't done it myself and sort of dismissed it because most of what I heard was that the relief was very short lived and not worth it...but a couple of people posted different experiences so it might be worth a shot if you don't have other options that you are able to try.

I'm very sorry things are so difficult for you right now. I hope they turn around for you soon. Take care.
