If you're in significant pain due to wisdom teeth, you need to get them removed ASAP. If you schedule now, with your condition, you should be able to get them out and be mostly recovered by vacation; you definitely don't want to go on the vacation with them still in. If you're scared of the surgery, ask for general anesthetic; you won't notice a thing. Recovery is going to be a few hours of having cotton stuffed in your cheeks to help stop the bleeding (it's going to be seeping, not outright gushing or anything), and a few days of liquids and soft foods while your gums are tender. You probably won't need to go in again to get the stitches out; they'll dissolve on their own in about a week.
