Hi, I'm a college freshman and as weird as this sounds, I had a piece of pizza and the crust was a little hard, and I chewed it and swallowed too fast, having a sharp edge of the crust cut the back of my throat. This happened on this past Friday, and it seems to not be getting any better unless I take some advil. Should I continue to wait it out? does it take longer than 4 days to heal?
