swollen cervical lymph nodes

in march i had tonsilitis. swollen gland with white patches on my throat. was cleared up with antibiotics.
in april i had 2 moles removed from my neck.
a few days after i was rubbing a stiff neck and felt a swollen cervical lymph node on the right side of my neck. apon further investigation i felt the similar node on the right side. when i pressed on it it hurt but it was not that large at all. maybe the size of a small  kidney bean or marble.
i went to the dr and he wasnt worried at all. i went back 2 weeks later and he still wasnt worried. i went back a few days later and saw his partner who also was not worried.
i went to the ENT who sent a camera up my nose and saw i had large adenoids (adenoids). not an issue he said.
he was not concerned withthe cervical lymph nodes either. he gave me antibiotics and i have an appointment in7 days for a follow up.
only when i press on them they hurt. they have not grown...well, when i play with them they tend to get a little bigger.
Is there something i need to worry about? can it be something and none of the drs have caught it? I am just wondering what could have caused these thigns to swell.
any input would be welcomed.
just keep the negative stuff out please. thanks
I have no symptoms of anythign else. i feel great, i exercise and have no loss of appetite at all!
