Don't give up. What you are describing is one of the many symptoms that I have gone thru over the years. My first flare up was in 1998. It started after I was injured at work by a patient. I first had the heaviness and fatigue with the muscle cramps. My next attack was in 2003. It the same way except that my legs felt like they vibrated. Now it is my right arm, leg cramps/vibrating, heat intolerance, stomach cramps in the left upper quad (they don't know what causes them. every possible test has been done.), and now optic neuritis left eye with major decrease of vision in right eye. I have had smaller flare ups inbetween that didn't last long. Just don't give up. Keep going until you get a dx. Hopefully this new neuro is the one. It took my primary doctors partner to dx me and send me for further testing. I'm not upset with my primary just disappointed. I told him he needed to start listening to his patients more. He said, "Vicky, you have always spoke your mind when it comes to your patients and told me what I should do. I should have done the same thing for you and I am sorry." Not many doctors will admit their mistakes. Most think they are God.

Sorry so long.
