I had a stroke 3 months ago which affected my left side. I also have lower back problems that my psychiatrist believes may be a slight bulge in the L5 area. We are using exercise to see if it improves. I sit for long periods but have become much more active. Over the last few weeks, my feet have been swelling with the worst being my right ankle/top of foot. It does go down after having my legs up for awhile, but the right side around the ankle of my right foot still stays swollen. The only medication I am on is Crestor for cholestoral of 107 and Aspirin 325. Could this be a blood flow issue in the legs or coming from the possible L5 issue.
