Kenalog Indention, Buttock, Fact of the Matter, Adverse Side Effects, Dermatologist

I was diagnosed with ga in September. My dermatologist wanted to give me a shot of kenalog. They never mentioned any adverse side effects.Now, four months later, I have a large indention in my left buttock where the shot was given. I went back to the doctor to have them look at the area. They said that they must not have given the injection deep enough therefore causing the atrophy. The doctor told me it would fill back in but that it would take a while. I am scared!. I don't know if it will keep getting bigger. It has started to ache a little bit. I have a feeling the doctor is just telling me what I want to hear. The fact of the matter is they messed up the injection. Doctor's should not be injecting this drug without explaining the potential side effects. Beware!
