i had resty injected into my lips about 12 days ago and also received a steroid shot, which significantly reduced the swelling. the mild swelling and bruising has been gone about 4 or 5 days. today, however, they became extremely tender and bruised feeling and are swelling a bit. they are also very chapped and sting constantly, even with lots of chapstick on. does anyone know what could be going on? i have had resty before and have never had this recurrance of swelling.
