i have recently found this bump that runs side by side my jaw its not under my jaw but kinda directly under my ear. i dont even know its there until i press real hard and i also check the other side and theres not one there. just on the left side. i noticed this a long time ago and i dont even know how long it could of been there before i even noticed it. Its really hard it feels like a mis shaped bone. its not real large but noticable when pressing hard. Sometimes i have a bit of pain in there that radiates up to my head but ive been going to a chiropractor with some bad neck problems. i had a ct scan done a couple months ago due to headaches and im wondering if a scan would of picked up a swollen node. or if this is even what it is. im wondering what else it may be though.

thanks
