Hello. I am 19 years old and i recently discovered a small bump in the center of my lower neck. I did some research and got several answers replying with some sort of lymph node, however im not really sure. It does not hurt, and it almost looks like a large zit with the center of the bump being slightly red. The thing is this bump is in a spot where a single long thick and dark hair on my back used to grow. It was noticeable by my mother and my roommate when i came back from the shower. So whenever it grew i plucked it because it seemed rather annoying being the only long noticeable hair on my back. Upon researching this bump i read something about some sort of hair follicle problem? Could this be what i have right now? Or is this some sort of tumor starting to form that i may need to get looked at? Any answers would be great. Thank you
