What to do with a cut in my throat?

What can I do about a cut in my throat? I can feel it every time i swallow anything. It's really been bugging me and I've had it for like 2 days already. Any suggestions as what I can do to help heal the cut? Anything that doesn't involve buying medicine? I was thinking of maybe trying to eat a lemon to possibly disinfect the cut but I'm no doctor... so yeah any help is appreciated. Thanks.
