Since that heart doc was good could you ask him who he could recommend as for more docs? The shakey maybe something from the heart and the arm issues.So maybe that test will give you more answers. I know how frustrating this is cause I have a lot of unknown as well. I'm sorry your feeling so ill but maybe if you call back that doc to get some more docs that he may work with. I know we have talked about team approaches and how they are hard to achieve. I will also say I have been to what are suppose to be great hospitals such as cleveland clinic and ucla and have expected more to really feel let down. I often feel they have so many patients they really don't work as hard as they should. I don't know the answer just your not alone.
