With reference to lymph chart

Okay, the green stickers indicate where lymph nodes are???? And, what does it mean when one experiences brief, sharp pain in those areas, or long-term swelling?

I get swelling of the anterior cervical nodes about once a year, beginning at this time of year. Every now and again, I'll experience a sharp (almost blinding) pain in the facial nodes. Could the roooomatizzz cause those symptoms?

Sheeeeesh, I'm feeling so good and falling apart at the same time! What a walking paradox, eh?
