At the moment I can barely stretch my arms or lift things because my arms muscle and joints are in agony...today I didn't do anything and they are just as bad as they were earlier...It's really hard to explain but anyway they hurt so much and I can't straighten either of my arms out properly! I'm not ill or anything and also I haven't done any strenuous exercise...I had a bath earlier but my muscles still really hurt...anyway ideas what it could be?
thanks
