I have been recently diagnosed with RA - about 3 months ago. I was devestated but then I realised that it made sense of my myriad types of pain and limitations. I went on methotrexate but I have not been on it long enough to see if it works. I have been on NSAIDs for almost 6 years! Then I fell I fractured my patella and needed surgical repair which was 3 weeks ago and am in a knee immobilizer. I am not sure about healing and RA myself but hope to see a rhematologist this week - I live in Bermuda so he only comes every few months! I will let you know if he says there is any problems with autoimmune and healing or indeed any link between the RA and the increased possibility of softening of ligaments which can lead to injuries like my OS suggested!! (no one told me that before, so not sure if its true!)
Take care and I hope you all get some answers soon.
