Hi...besides The Fog, burning is my major pain symptom. My thighs burn almost all the time, my back and my 'arm flab' too. The only thing that relieves it is soaking in a hot bath tub. You said ice helped yours but cold makes mine worse. Don't really have an answer for this one...just wanted to tell you I get this too!
I suffer from intense burning in my neck which seems like the nerves , the pain kept getting worse until intolerable. Muscle relaxants helped a little but eventually I went to a pain spec who also specialises rheumy. I had no choice but to wear a narcotic patch and now I am almost pain free, enough that I can manage. Lyrica helps also and muscle relaxants.. but eventually I needed more but I still use the lyrica and valium. Hope I have helped, to me it felt like nerve pain and always refered to it as that with my doc separate to fibto.good luck with it and I hope it doesnt worsen. sue2z Heat packs helped in the early days I have ones full of wheat that you heat up in micowave.
