I haven't posted in awhile. I have Fibromyalgia and Chronic Fatigue, diagnosed a long time ago I have been having all sorts of problems. Longt story short, I had to have tendon surgery in my ankle and docs think I developed RSD in my foot. It burns, turns red white and blue and swells alot Ok, so I had a lumbar sympathetic nerve block 2 weeks ago, and will probably have another next week BUT, the burning is now in my arms and legs. I know RSD can spread, but I am wondering if it is something else. This feeling feels familiar. It feels like my skin is sunburnt and very sore to the touch. It is intermittent To confuse things, I have a lot of cervical spine issues and tendonitis in my arm. Also, 3 weeks ago, my ANA was elavated and my Smith Antibody was positive, possible Lupus Could this just be the fibro? Anyone else experience this burning sore skin pain?
