I then chewed some gum for a couple of hours (same piece), then noticed my
tongue hurting
a bit. Looked in the mirror and there seemed to be
a kind of ulcer thing. Checked my tongue today and it's seems to be gone/not hurting as much. Anyway, what I would like to know is, is there a chance I could have caught anything from the kiss? Would the ulcer type thing on my tongue have been caused from the chewing of gum?
