I have pain, swelling and bruising in both my feet and ankles. I know I have mild arthritis. But, this came on kind of suddenly this past weekend after probably too much activity, which for me, is just walking too much. I walk a lot at my job, but now have a rollator due to my arthritis. My left foot is swollen to the size of about 1/4 of my right foot. Same for my left ankle. And the bruising, etc, is painful.
