I had the same problem with prednisone and it lasted for two weeks after I came off the nasty drug. I was swollen from my knees down. It looked weird and it was very difficult to walk. I hate prednisone!!! I have been off it for over a month and now I am fine. I hope it is just the prednisone in your case too. Good Luck!
