NEED HELP ASAP?

Anonymous
OK so I've had a swollen lymph node under my jaw for 2 months now and it doesn't hurt at all. But, at first it started off with 2 lymph nodes in my neck that were swollen and aching really badly so i went to the doctor for those and they gave me medicines to take.. now that those are gone I've had this one under my jaw for a few months but no pain amd i haven't told the doctor about this one yet. What could it be? I've also been having other symptoms that i think is related to a thyroid problem but my mom says im too young for thyroid problems 😒 and no one believes me at all so i have no help. But this is my body and i know when something is wrong? Can someone please help?
