There's a ton of work involved in diagnosing a patient, as well as treating them. To start off, there are tons of skin diseases out there, but not only that, you have to know the stages of them, how it spreads, all the types of antibiotics and how it's made, what it treats, how much to give them....etc. You guys get the point right? My question is do all dermatologists know everything right off the back, or do they have to refer to some sort of guide? Is there questions patients asks that they have to think about or don't know the answer to?
