I am so glad that I found this site.In Aug 07 I went to my doctor with complaints of headaches and severe allergies.Next thing I know a nurse comes in and tells me she is going to give me a shot and that she is best on the right buttcheek.My only answer was "ok" there you have it! It wasn't any more painful than any other shot I have received in the past.The next day was a different story.It was very painful to sit down or to put any pressure on my right side.Then in Oct I noticed a very small indent.Just like someone else had posted, I just figured It was coming with age.Now in Feb 2008 it has progressively gotten larger is discolored and aches.I have been very worried that there is something seriously wrong with me so to find this site was a little comforting although I do not wish this upon anyone!!
