If your stye lasts longer than a week or two, or if you develop more than one stye, you should see your doctor, says Heiting. A doctor can prescribe antibacterial eye drops or ointments and -- if necessary -- oral antibiotics. If you've got a stye that rivals the size of your worst pimple ever or is superpainful, Heiting says your doctor may make a tiny incision near the stye to drain it. In case it wasn't obvious, do not try that at home.

Sorry, makeup mavens -- you're going to have to live without your perfect cat eye for a week. Heiting says to skip all eye makeup, and wear glasses instead of contacts. And keep your mitts away from your eyes, especially if they're dirty.

Just remember: With the right care, you'll get rid of that nasty stye in about week at home.
