Weird Pimple/Boil I don't know what you would call it.?

Its on my face in the middle of my cheek. I can squeeze it and a little puss comes out but it still looks like its filled with puss. Skin grew over it? I tried to pop it with a needle but it didn't pop. I poked it where it looked like puss. Its white, not green or yellow. the first time I popped it came out solid puss then it turned to liquid. I've had it for months. I remember it was a pimple at one time then I popped it. I have eczema but I know this isn't that. A boil is something caused by a hair but uh... I have no hair on my face. I don't want to go see a doctor. I need this thing gone by June 5th.
