It IS unusual for it to be slipping after such a short time after surgery. If I were you I'd get another opinion, although another doctor might be reluctant to give you advice since someone else did the surgery. This could be a sticky situation, but you REALLY need someone else to look at you.
See if you can get a referral to someone else. Seems to me that your surgeon didn't do a "real good job" when he operated on you. But that's just my opinion, and I'm no doctor.
Please keep us posted, ok? I wish you the very best. Hugs, Lee
