I stubbed my toe and it split the nail and I had to cut it off, now its very swollen, red, and infected. My whole foot is swelling up from it.

See doc now! An infection that is spreading is very serious. Go to an ER or UC now. You don't want it spreading farther!
Why R U waiting. Sounds like a big time cellulitis is brewing. I hope the nail is what you cut off and not the toe. You have but one choice now. Before things go from bad to worse, get to the Ur, ER, of a physician. Fast.
