Hi clcurran. On top of the excellent information from Reggie, I also want to mention Raynauld's Syndrome. I noticed that you mentioned that one of the symptoms you are experiencing in your feet is coldness and Raynauld's, which can often be comorbid with RA, is characterized by cold in extremities. This article from our editorial team goes into further detail: https://rheumatoidarthritis.net/medical-conditions-occurring-along-with-ra/raynauds-syndrome/. Of course, this is a symptom, particular this time of year, that can be caused by a number of things and only a doctor can provide proper diagnostics. Hope you get some answers and relief soon. Best, Richard (RheumatoidArthritis.net Team)
