I have been ill for over a year now. I have constant joint pain (knees, ankles, fingers), muscle aches, chest pain, and abdominal pain. I have had elevated CRP and ESR since the onset, and a CT of my sternum (which is where the pain started) showed degenerative changes to the manubiosternal joint. Labs haven't really found much else (RF negative, ANA negative, anti-CCP negative, celiac negative). NSAIDs do nothing, but steroids have helped, but only on short term trials. After sending me to a bunch of other specialists (who found nothing), Rheumatology has decided I have some kind of autoimmune disease and I have been started on sulfasalazine. Anyone have symptoms like this and been diagnosed as autoimmune? What kind of autoimmune causes these symptoms?
