I've been in the hospital and rehab with swollen feet. The left was the worst about double in size, red, warm and extremely sore. At first they thought it was cellulitis and then a biopsy was taken from the top of my right foot to try to check for vasculitis. I am going to be sent to a rhymatologist for further evaluation. It was not determined what I have only my sed rate was high and the uric acid was a little elevated. Any ideas what it might be?
