Do people with UCTD have flares? With this sudden back/hip/pelvic pain I've been having (no injury or heavy lifting) along with more fevers and more not feeling well, it hit me a couple days ago that I may be having a flare. BUt does UCTD flare? Could this be what it is? I had an MRI and am going to PT for my back now, but I still have to wonder.
