I also have this problem in my buttock after a shot of Demerol and Fennergin when I went into labor more than 2 years ago. I have had Kenalog shots since then in the same spot but the doc. contributes it to the first shot years ago. The spot is about the size of a tennis ball and there is another smaller spot underneath the big one that is the size of a quarter. I have noticed recently that the large spot is spreading. There is now an indented line forming from the large spot and going around my hip. I recently had a biopsy done and they confirmed that it is fat necrosis. Like you said, there is nothing we can do to make this go away, only cosmetic surgery. I don't know what my doc. plans to do next. Do you know if there is any type of legal action that can take place considering that this has not severely f'd up my 'nice' ass!
