I have just finished a course of antibiotics for an ear infection and now have a sore in my ear that appears to be a sore that has become infected. I have also got arthritis in my shoulder which is flaring up and exzema down both legs and on my back and in my ears which is now worse than ever. I have been on insulin since November and have just changed to a different form of insulin as the nurse thinks I am allergic to nickel - where has that come from? I am trying to lose weight but what else can I do - my ear is agony and my shoulder is constantly painful - the pain going down my arm to my hand almost all the time
