Hello, long story short I have a lump under my jaw it's been say about 3-4 months I've noticed it a while but never took notice, Searched it and didn't panic to much as cancer this young (23) is not very common. But as times gone by I can't say if it's gotten bigger or anything but it's got painful ish I'm noticing it alot at night time mostly I start sweating from the pain it's like an electric shock pulsating feeling. I just thought I'd see what's up with it I'm going doctors tomorrow about it but I just wanted to see if anyone can put their finger on it maybe some advice? Thanks people o started panicking when i noticed it was starting to get painful
