I have had a low white blood cell count for years. Just in the last year I found a doctor that was willing to find out why. She did all kinds of tests on me, but they didn't find anything. I also suffer from joint pain and discomfort all over my body. At first she said I had RA, which would explain my joint pain and low white blood cell count, but now she says I have Fibromyalgia because the tests for RA came back negative and my hands don't look like RA hands. I tried to tell her from the research I've done I can have sero-negative RA which would mean that I would be less likely to have the nodules she is looking for but doctor's know best apparently. So I guess my question is, can it be fibromyalgia or does it sound like sero negative RA?
