Joining this wonderful and supportive list a few years ago has made me realise how minor my symptoms are. For me it’s only a couple of fingers and a few toes that have been affected and MTX is by and large keeping it under control. I am experiencing a flare up at the moment but compared with previous episodes the impact has been small. However, I have also developed some swelling on the inside of my left knee. I’ve had this problem once before and it was successfully treated with physio. At the time I put it down as an exercise injury but now I’m wondering if it could be linked to PSA. So I’m trying to decide on the best place to go for advice. If it could be PSA then perhaps I should go back to my rheumy. I appreciate I have only given a vague description of the symptoms, but is swelling on the inside of a knee a typical response to PSA in the knee itself?
