I just got back from seeing my GP hoping he would refer me to someone who would test my heart (I read about the mitochondria and how it relates to undiagnosed heart problems) and he told me that there is no reason to go into further testing because I have not presented with pain or shortness of breath. He said that I do have CFS and that I should be happy that's all I have! I am happy that I do not have anything fatal, but I am still undr the belief that something has been missed in all these blood and neurologic tests. I want something that can be treated! So now I am ready to say Uncle and let it go after my GP, Rhuemy, and nerologist all say CFS. But I don't WANT to give up! At what point should I stop searching for a true diagnosis? Sometimes I would RATHER drop from a heart attack than have to live like this! Sorry for the rant, but I am just so disapointed and in tears over this. When did you all give up?
