I have had a small lump in the lower left side of my neck for about 12 years now, it its (kinda between my muscle and collar bone). It used to only bother me when i would go running. Now, twelve years later it hadn't changed till recently, it is still the same size and hasn't bothered me in like 12 years now. A couple of days ago, it became swollen and hurts? when i first realized it back then, (12yrs ago) i saw a doctor and he just felt it and said it was nothing! .Now i have no health insurance so i wanna make sure its something i should REALLY get checked out before i start racking up the bills. What could this be? How do i know if its serious? Oh and please DON'T correct my spelling, i know i can't spell to save my life! But i don't need a spelling lesson right now, i need some answers if there is any.
