Welcome to our site, - the burning of your arms and legs sounds very painful and quite irritating. I'm sorry you're going through this sort of pain. Have you been to an orthopedic specialist? It may be several different things. I know when I mention a pain or issue about my body to my rheumy, he refers me to my orthopedic surgeon/specialist and a pain specialist. And usually, they are the group to help me deal with it or resolve it. I am currently scheduled for surgery to help resolve the weakness and pins and needles sensation in my arms and hands. It's been going on since August. With a referral for an MRI, I have slipped discs and blocked nerves in my cervical spine. Maybe this would be a direction to go in next? I have a circle of physicians who treat me - do you have a community or circle of physicians who keep an eye on your medical care? I hope this helps. This link to an article may have some useful information. Wishing you the best - Rebecca (Team member)
