I've been told for years that I had FM, and despite infections out the yahoo, and other things, I got all the platitudes about FM and it being in your head, etc. Dr. Salvato had helped me a lot, and told me that she felt that I had CFS, with FM. Two years ago, we found that I was adrenally suppressed and my B lymphocytes were low, but we felt it was from having had steroid injections in my spine. I received some IV IG's and was better for a while. Then, the severe fatigue and the infectons started. She did the testing for subclass B lymphocytes and three of the four were really low and the other a little less low. I had the stimulation test and nothing moved!!!! We now know I have primary immunodeficiency, usually found in childhood or in the teens, and a SERIOUS, SERIOUS PROBLEM. I would encourage all people diagnosed with FM and CFS to be tested for this. It is genetic, but comes in varying degrees and it is SERIOUS folks. I confronted one of my docs, who had given me a hard time about FM and CFS, and he was SPEECHLESS. I pointed out to him that he HAD FAILED TO DIAGNOSE ME AND HAD IGNORED MY VERY CLEAR, SUCCINCT DEPICTION OF MY PROBLEMS. I told him he needed to start listening to his patients, stop being a bully, and stop being so pig-headed, and that he needed to do this testing. It is a blood test, no risk involved, and once you get a diagnosis like this, YOU CAN GET HELP, AND THEY ARE FALLING ALL OVER THEMSELVES TO RECOGNIZE HOW SICK YOU ARE. The DISABILITY COMPANIES SURE CAN'T GIVE YOU ANY PROBLEMS ONCE YOU HAVE THIS DIAGNOSIS.
