I am female in mid 40's, recently have had polyarthritis, raynaud's (in my feet) in the past few weeks. I have a chronic soft tissue injury to both wrists(~5years). I'm currently being treated for these problems, but now have polyarthritis symptoms. I have had persistent oral ulcers on the soft palette 2 months ago(resolved now) that followed a severe viral lung infection.
