I received a shot of what I thought was my regular prednisone steriod in November 07. Obviously, that wasn't the case. I must have received this Kenalog shot because now I have a golf ball size dent in my upper buttocks. It is not going away and I think it could be getting worse more than 9 months later. I would be interested in a class action lawsuit against the manufacturer of this product and/or my allergist. Please contact me with possible ways to make this look less obvious. ****** Thanks Tori C.
