I think it's the lymph nodes, but not quite sure. Whenever I touch that certain area behind my ear and in front of it (like on my jaw bone kind of) it's rather painful and tender. Same with my my underarms, painful when I touch a certain spot. I'm feeling perfectly fine, no flu or virus or such. I am however, on my period, but I don't know if that might be the cause. As I recall, I have had the same pain in the ear area a few months ago and it went away after a few days. They don't look swollen, but feel a little like it. What could be causing this?
