"Like most of us, we get regular bloodwork done. My test results came back very good, except a surprise. For some reason I am close to testing postive for the thyroid perox auto AB test. Upon googling it, this is Hasimoto's disease which is very common with RA patients. I have a lot of the symptoms but not all. It does explain alot if indeed I have this. Anyone else experiencing this? I don't see my rheumy for another 2 weeks. thank you."
