I have suffered a pain in my upper back, left side of my chest, above my knees and the left side of my anus. I also have very crackly neck and back. The pain in each area feels the same; there is no redness, lumps, or anything that appears on the skin that would suggest an abnormality however, when it happens even thin clothing just covering the area is too sore to bare. Only the slightest touch even a feather brushing my skin is excrutiating. I cannot think of any thing that would result in such symtoms and other than that i am in good health. Please if someone has any idea whats causing this, reply to this blog. These pains are not constant but when they start they spread to these key areas and there is nothing i can do to relieve the pain i jst have to wait untill is goes. Plx reply, thanks.
