yes I have learned the hard way due to this! It has affected me all over - agonizing pain, eye sight problems, skin problems, energy levels, gall bladder pain, palpitations and tons more. When I have tried to ask the doctors about more than one symptom they have been tetchy with me and so have never seen the big picture. I've been fobbed off for months and probably years with stronger and stronger pain killers. One doc wanted to give me steroids with no evidence of polymyalgia at all. I am so very angry about this and now a latest batch of blood tests looking for lupus, muscular dystrophy and a few other ailments have gone missing. The receptionist wanted me to see the GP about it and I burst into tears, there is no way I am going near that woman again. She was horrid to me last visit. My hubby took me to her as I was in such a state. She folded her arms and said I have had 5 injections, that was enough and lots of people have to live with pain like mine. Thankfully the doc at the B12d charity has been so kind and helpful to me, he has seen all my blood tests and list of symptoms and actually listened to me. Nice to be able to have a rant somewhere - so thank you. I will be seeing the endo, who is a new one, tomorrow and I have my file of information to take with me.
