My general doctor did 2 or 3 complete blood work ups. Each time my RA factor would elevate slightly but not enough to be considered to have RA (has to be a 13) and I would have a positive ANA. Now I am seeing an RA specialist, my RA factor is 12.6 (I believe, I would have to look at the results again, I know it's pretty darn close) & my RnP is 1.9 so she sent me for a Nerve Conduction study. Although the study came back within normal range that doctor said I have Mixed Connective Tissue Disorder, just in the beginning stages. He said that because of all of the other issues I am exhibiting....extreme fatigue, pins and needles, sensitivity to cold, muscle weakness, IBS, mood swings, can't focus, bad memory, scoliosis, can't tolerate bright lights, have trouble "operating" my hands after so long.....that's all I can think of right now. After the results of the Nerve conduction study my RA doctor said I don't have Mixed Connective Tissue Disorder. The other doctor said that I do, but the early stages. I don't know what to do.
