So my eye has been swollen for two days now and it keeps getting worse. It's starting to dry up at the corner and water more in towards my nose? I have crust too? Could it just be a stye or something else? I have an appointment for Monday but wanted to know what you ladies think cause if it is a stye I can just pick up some stye medicine
