I have a fast growing lump under the jaw (left side) about 1'2 way back, and it is heading inward and getting larger. Almost getting uncomfortable. It was a small lump for about 2weeks, just thought it was a hair foolivle abcess and would go away, but just last 2 1/2 days started to really get bigger quite fast. My dentist noticed a hardness on on of my saliva glands inside my mouth last year, that sometimes gave me discomfort. Could this all be related, and what is most likey .Thanks
