Until now I had no idea what the dents were on the lower back just above my right or left buttock. I have gotten Kenalog shots on both sides for allergies for the past 10 years! It first appeared on the left side then went away. Now I've got one on the right. It really doesn't bother me since it's covered all the time, even in a swim suit. However, this side effect cannot be good and I will deffinetely not be getting Kenalog shots anymore... but to anyone who is worried about it not going away: it did for me.
