I had a cortizone shot in January of 2003 which was Kenalog and I had a huge, ugly indentation in my hip also. It was at the injection site. The good news is it has almost totally disappeared now but it took a long time - about 2 years. There is no more indentation in my hip but I can tell where the mark was because the skin looks slightlky different there but not too bad.
I've got a scar on my hip too...but it hasn't gone away after many months. If its still there next summer, I'll sue the doctor who injected me.
