The other day I noticed a lump on my neck on the left side right under the jawbone and ear. I measured it and its 2 cm in length and i cant move it. I can move my neck left and right just fine but when i move it towards the right I feel pressure on the left side where the lump is but no pain. I thought for a few days it would become a very bad pimple since I suffer from acne and it was very itchy and still is on that spot but there was never a whit head and it feels too big. There isn't any pain and it feels really hard. Its not on the surface but a bit deeper. I've had mono a few years back and I know what swollen lymph nodes feel like but all the other lymph nodes on the neck, armpits, etc. are fine and not swollen. I have been tiered for a month or so, feelings of depression, loss of appetite somewhat, and nauseated on and off. I basically have no other symptoms. I'm not pregnant, running a fever, or anything like that. I'm 20 years of age and a bit nervous since I've read on some articles that talked about cancer and lumps like this. This year has been unusual for me because I never get sick and I've been on and off antibiotics this year. Also, I had what seemed to be like pnuemonia (but wasn't) a few months back and have noticed some minor chest pains here and there since getting better. If anyone could help, i'd really appreciate it.
