My right foot has never been involved with much except suffering the side effects from my meds. As can been seen my foot is suffering from edema. The edema gets so bad that my shoes don't fit. I'm forced to wear sandals or athletic shoes with loosened lases. It comes and goes without warning. I can feel it in the morning when i get up because my feet and ankles feel "tight". I am supposed to be taken off the Prednisone over the next few months because I'm being introduced to a new drug. By July or August I should be totally off the Prednisone. I sure hope so.
