Last week I had a significant flare up. I could barely walk, my hands were swollen, I could not bend by fingers, my right knee was swollen and multiple other ailments. My doctor ordered multiple blood tests. I was convinced that something would come up abnormal as I was feeling so bad. However, all tests came back withing normal ranges. I have seronegative RD. Is it common for bloods to come back normal with seronegative RD even during a flare? I feel as though others think my ailments are in my head if there is no proof in the tests. Frustrated.
