I cannot remember all the tests they've done, but they were always searching for some reason for my body being so weak. Even tested for TB, vitamin deficiency, brain problems, lung problems, since I had one lung totally collapse in the past. I do have fibromyalgia, which we know causes CFS, but this is way beyond fatigue. Several skeletal problems, but that's not causing the weakness, of course. I don't have the results yet from the nerve/muscle test, but I don't expect anything at this point.
They have sent me to several specialists, but no help at all. Needless to say, it is depressing.
