Hi, I recently can feel swollen lymph nodes in my neck right under my jaw on both sides, they seem to be painless and fairly moveable but are slightly visible to the naked eye when I lift my jaw, I went on a Google rampage and am really worried, I don't really get pain when I laugh or breath deeply tho neither do I cough blood, as it's winter I have the occasional cough, I'm really worried that even tough I'm only 18, it's somehing serious and I even went to my GP who said that he can't feel anything bad last time he checked, it's been 2 weeks since then and I went to my GP again and still he tells me he can't see anything wrong, this time not checking my lymph nodes, it's driving me crazy, the lymph nodes feel firm but rubbery and relatively moveable, I can't really detect them growing.
