Thanks both for the links, they are really informative ones. I have had the EMG, if that's where they put a needle into muscles to test muscle function then i have had that twice alongside the Nerve Conduction test. They both came back clear. I don't know how else to measure this when both tests come back clear. I am sure its muscle rather than fat as the loss is very disproportionate, my bum which is worst has lost all padding so that it's awful sat down on it, like sitting on skin and bone with awful sfn pain thrown in.
Does anyone know if there is any other way to show what's happening with the muscles? The links refer to emg and nerve conduction so is this all that can be tested do you know? :-(
