For many years I have pains that pop up for no reason in joints and muscles and last for usually three to six months
and then vanish. I get rashes
and tiny red spots on my shins
and then clear up. The rashes last about the same three to six months. I had these pains in both my shoulders at once, which almost never happens, so I thought it was my rotator cuffs going due to the work that I do.
