Hi JeshuP. You are not alone in wondering if there are specific causes or triggers for RA. At this time there is no know cause of RA, but there is considered to be a genetic risk factor, as well as potential triggers. While I can't speak to the specifics of your situation or the conditions that you suspect may have been triggers, I want to direct you to this article from our editorial team on potential causes and risk factors: https://rheumatoidarthritis.net/causes/. It notes that infectious agents are considered potential risk factors, but without conclusive evidence. Hopefully others will chime in with their experiences. Best, Richard (RheumatoidArthritis.net Team)
