I got a black eye a while ago during a blackout bender and didn't care or even try to take care of it--I just picked up another bottle. Today, sober, I got the tiniest, tiniest rash and I was rubbing cream all over that.
Just remember how wonderful it is that you are taking care of yourself now. That you are sober and are going to a doctor to get checked? If you're anything like me, not so long that would have been unimaginable!
