Hello There Thanks for your time

for 5 weeks now i had swollen nymph nodes in my neck they went down doc said could be fr a pimple scratch bug flu anything not to worry but i did
then that leading to anxiety ( mild now) but my worry still is
i had all blood work done all came back good normal white cell count normal all nodes went down but one wee one in the hair line back of the neck small he said, now to be concerned a normal node i feel it there then worries me then it kind a get hot skin burns a little then a weird feeling going up the side of my head , anxiety or nerve i ask doc he goes oh thats just where the node is pushing on the nerve a little.
too small to cut out normal for me to get use to it but i still feel worry is it normal for one not to go all the way down the burning the skin on the neck stress? thanks for your time i do appreciate it
