Probably not a good idea while your fingers are bleeding, but have you ever tried hot sauce? I used to compulsively suck my ring and pinky fingers until I put hot sauce on them to stop. I know what you mean about doing everyone's dishes. I absolutely cannot have dirty dishes. If it's in the sink, I wash it by hand, even if the washer is empty. I made a post about my possible OCD, I get what you mean about imperfections on the face. I get that way, too.
It will get better in time. How long have you been taking the medicine?
