Yes I have had one very recently, nothing on there that seemed to concern anyone. Had emg, ncs, myasthenis gravis bloodwork, lyme tests up the wazoo, sed rate, ana antibodies, RA factor, you name it. Mri of l spine, I do have some probs there, with legs, sighs....well I get it about the biopsy now. At least maybe they will do something else if it is positive. I hope. If there is even anything to be done? What could they do about arm and leg fatigue. I could live with it I just want to know WHAT it is called. I want a Name for it. I'm tired of being a blob of unnamed symptoms!!!!! Though I am realizing more and more that that is what they all want to say!!!!! Plus maybe the tilt table will help figure out something....I found out more about that it can actually show lots of stuff......so lets hope Something shows up this day of tests. I went to their web site and learned alot about it....though have had before...
