my 9yr old daughter received a shot of kenalog in sept. of 05 after a sever case of posion sumac. on night she showed me a dent in her butt about a 1 cm in diameter. i thought nothing of it as she said it did not hurt.. she is very active in gymnasitcs 4-5 days a week -- so i assumed it was a demple. last week she was getting in the tub and i noticed the dent it was now about 4 cm. my husband and i were so upset wondering what could this be (not thinking anything about the shot she received a couple of months ago) and trying not to upset her. as soon as the dr saw it he knew what it was. we should have been told of the side effect! it is now peace of mind knowing she's is not alone and will be ok. but, now wondering how scared will she be.
