I usually post in the fibromyalgia forum, because that's what I have been diagnosed with a year ago. I have some symptoms that my doctors tell me thats not fibro but they have not tested me for MS yet. When I get physically active and it gets to the point to where I am doing to much when I get over heated on the inside I start getting dizzy, slight headache comes on, nausea and total fatigue. I feel like I have been drained of all my energy, and I get short of breath and my concentration and thinking get fogged and I can't just think or come up with what I want to say. I have to go lay down. I kinda feel like I have a 24 hr bug. I have told my gp and rheumy and they both just shrug it off like it's nothing. BUT it is a symptom of something, healthy people don't do this. I don't have high blood pressure, otherwise healthy that I know of, haha. I only take otc meds when I really need them. I have been told that it's pushing myself with the fibro, but I don't hear of alot of people getting this, just a few. I just thought maybe ms. I don't know if you can have fibro and ms together. My md did want me to see a neuro doc to rule out ms but he doens't think it's that. I was just wondering, thanks for any help.
