I can understand you'r situation; I don't have MS, but for years I was told I had Fibromyalgia, borderline lupus, Rheumatoid Arthritis , etc... I was tested for lime about three years ago and the results came back as negative. I may ask my Doctor for a lyme test. It can't hurt. I have been diagnosed with systemic mastocytosis, and it is very rare; it's symtoms can mimmic many diseases/conditions. Thanks for the information.
