Hello there, I was recently diagnosed with MS. I have had several symptoms but since I was diagnosed about 4 months ago I have had a almost continious burning sensation on my back. My neurologist says it is not a typical MS symptom, but it could be the stress of the diagnosis influencing my muscles.
