I have a big pimple on my nose! Help!?

Ok so I've had this giant pimple on my nose for about 3 days, and it's bigger than ever! I tried popping it because I see some whiteness(puss, I believe) but when I try popping it NOTHING comes out! And once that's done it hurts like hell! What can I do to turn this giant red blemish in to a white head? I have a date on Saturday and I need it gone by then! Please help! :)
