Okay.. what does it mean when your lymph nodes hurt?

Ummm, I would say to ask a Dr. I'm not too keen on illnesses but from what I know it could possibly be something serious.
It could mean you have some type of infection going on. A month is probably too long for pain. There are different types of infections and different antibitoics works for one and not the other. Maybe seeing your physician would be a good idea?
IT CAN BE ANYTHING FROM A COLD TO BEING A BIT RUN DOWN, IF THEY ARE HURTING TOO MUCH GO TO THE DOCTOR AND GET SOME ANTIBIOTIC'S.
