Having had shingles 3 months ago I am suffering all the pains of PHN in both shoulders, arms and hand and on the chest where the rash was. I am also concerned by other symptons, Loss of apetite: I feel starving hungry but having eaten a couple of fork fulls. I feel totally full and sick. I have lost over a stone in the past month. Lack of energy. regular bouts of diahroea and after sitting down or sleeping in bed, I have a very bad pain in my foot and have trouble walking for a while. This is all totally new to me.
