Hi northlake. While bruising is not generally considered a symptom of RA, it does occur as a side-effect of meditcations. In particular, prednisone is known to cause bruising. This article from one of our contributors looks at this issue, including some photos that look a lot like what you describe: https://rheumatoidarthritis.net/living/finding-beauty-bruises/.
In addition, this article from another contributor focuses on issues affecting the skin, including bruising: https://rheumatoidarthritis.net/living/beauty-skin-deep/. Hopefully some others in the community may also have some information to share. Best, Richard (RheumatoidArthritis.net Team)
