Hello. About 6 months ago I noticed a small
lump, about 1 cm in diameter, around where the submandibular lymph nodes are supposed to be, just under my jaw line, halfway between my chin and ear on the left side. It is firm, smooth, non-tender, and most interestingly, fixed into the muscle. Note that it is not technically enlarged according to most standards I've read about.
I found something "similar" on the other side, so I did not think much of it, just watched it closely.
