I have a super swollen lymph node about the size of a small grape under my chin on the left size. I was swimming yesterday and jumped in and hit my neck on the water a bit and it hurt that would be the only explanation I would have as to why it is swollen. It’s really scaring me though because it’s huge and hurts quite bad. I keep thinking it’s serious and cancer or something. Hoping it goes away soon. I don’t know if lymph nodes swell up after being hit or what? Idk if I need to go to the doctor or if that is silly.
