Ive had "stomach issues" for over a decade and on and off knee pain for about 7 years. Since April of this year ive had back pain that's worse in the morning and during inactivity. Bending is especially painful. Ive had an MRI and x-ray which showed no damage and my HLA B27 test was negative. Ive also had what id describe as my eyelids feeling really swollen(but no eye pain) that a steroid drop cleared up. Ive also had extreme fatigue at times (2 energy drinks and 2 naps multiple days a week when it was at its worst) and what sounds to me like brain fog (telling my husband the same stories multiple times and slurring my words a bit when talking and trying to get my point across. My rheumatologist said my symptoms sound like classic AS and has started me on sulfasalazine and meloxicam (naproxen didnt work for me) despite the above testing all being negative. Im wondering if people that have uveitis from AS all have pain or some experienced the eye swelling feeling instead and also how to get a diagnosis when the testing mentioned above is negative. Thanks in advance!
