 Yeah, so I'm an ER doctor. I'm there. We're open 24-7. We're always there for your questions. There's no such thing as a dumb question. I think people have a good instinct about this, but if you're a wound, once you put that dressing on it, if it's getting red, if it's getting worse, if you have a fever, there's streaks on it, it starts to smell bad, or if there's pus coming from it, that's when it's time for you to come in and see us.
