I also had a reaction to a kenalog injection in my upper right buttocks area. I have a HUGE discolored indention that has not gone away. It has been a YEAR!! I also had irregular periods for three months with ultrasounds, etc. to make sure I was alright. My doctor did not think to ask me if I had had a steroid shot lately. I sure didn't tell her because I had no clue it was a side effect. I had the shot for severe allergies and was not warned of the side effects either! I am very against having another shot, even though it cured my severe allergies last spring. I look deformed!!
