Has anyone else here with JIA experienced severe back pain that lasted just 10-12 days then relieves without medications?
Could it be due to a new exacerbation of RA or the first onset of a new autoimmune disease?
Hint: my RA supposed to be controlled with medications, and it's the first time I’m experiencing back pain and with such a character (there is no morning stiffness as usual, and it starts with standing and/or sitting for long periods of time, and relieves by changing the position into the opposite situation) then the pain disappeared suddenly without medications.
