I have had very bad back pain for the last 2 months....and about a week ago it subsided. and now ive noticed my left arm feels "hot" and tender, basically as if my arm was sunburned....I heard that it could be a nerve?
My dr. told me it may be shingles, but theres no redness,swelling,rash,or bumps.....so Im highly doubting that...Could it in fact me a nerve? How can i treat it? and how long does that normally last?
