Hiya. I'm 19 years old and Ive got the exact same problem. I found a lump, slightly to the left, right underneath my chin. I found it almost 2 years ago. Ive been to the doctors since and he said "I'm too young to have cancer". So I sort of pushed it to the back of my mind until recently it grew to the size of a ping pong ball whilst I had a cold. It has since shrunk again, but is still very clearly there. 
it doesn't move and is solid. 
please also keep me updated on your situation because I am petrified.

Im seeing a head a neck Doctor next Tuesday so I will let you know they gave me some antibiotics to see if it would go at first but nothing happend and had my bloods taken a few days ago I will let you know how it goes
