Suddenly I started experiencing burning deep inside my vagina. The pain seemed to come out of nowhere. It happened about half an hour after I used the bathroom, although I did have some slight tingling immediately after. The pain is absolutely awful, if it's a UTI it's by far the worst I've ever had, I'm not even able to sleep. I won't be able to see my doctor until monday, is there anything I can do until then? Better yet, anything I can do NOW for relief without needing supplies, as its very late...?
