Hard lymph node ?

im 18 years old and i have a hard lymph node trailing the back of my collar just where on earth the hair vein starts for about 3 years immediately. its small pea sized kinda hard have not changed in sized. i be to 3 doctors and they all told me that it be nothing to verbs about and my doctor said he even have a hard node trailing his ear. i had 2 blood trial done by 2 different doctors, i did a full blood count test, to check my red and white cell, and sugar, liver, pee test, blood pressure, heart rate, everything and he said adjectives my blood work and everything else was unflawed, they both have even feel that node and said its englarged a little other consequently the other node but thing to be worried just about. i read on the internet that hard lymph nodes process cancer or something and its freaking me out even after all the blood work and 3 doctors recounting me im fine. they took the node out or tested it but hes telling me by blood work and intuition the node themselfs im fine. should i be worried still ! i still freak out Well since you have be to doctors about this - I am going to read aloud just relax. I have one a few months ago on my jaw by my ear and I go to the doc and they just told me that it would be in motion away. So since all the test came pay for normal - simply ignore it
