So you have a rash and you're trying to figure out what it is. More importantly, you want to know what to do about it. You've come to the right place. This article is designed to give you a starting point with general rules about rashes. It's not designed to diagnose a rash. That takes eyes. These rules should be used like a map. A map is not the destination itself. Rather, it's a tool to help you get where you need to go.
Rule #1 - Frustration With RashIf a rash really bothers you, go see your doctor. Period. It doesn't matter if it's a common skin problem, or other people aren't concerned about it. You're the one who has to live with your skin, so if you want to talk to a doctor, do it.
Even simple or easily treated rashes can cause an immense amount of frustration if you don't know what to do about them. Imagine not knowing you have athlete's foot. You may be able to tolerate itching and burning skin for a few days or weeks, but you will probably reach the point that it drives you crazy. The solution may be a simple over-the-counter skin cream, but if you don't know that, the cream doesn't do you any good.
Rule #2 - Rash TimeGenerally, the longer you've had a rash, the more likely you need to see a doctor if you're concerned about it. Deciding if that mole you've had on your skin for the past twenty years is looking cancerous or not is something you want an expert to do.
Most of the time a rash that has been present for a couple of days will go away on its own. Warning signs that should send you to the doctor sooner rather than later are pain, rapid swelling causing shortness of breath, bleeding blisters in the mouth or eyes, skin that is rapidly turning dusky or black, and large amounts of skin peeling in sheets. As you can see, using rash rule #1 of frustration will get you to the right place.
