I've had pretty swollen lymph nodes in my neck for quite some time. I'm assuming it's tied to the post nasal drip I often experience, which I believe is caused by allergies. Any one know if swollen lymph nodes are a common symptom of allergic reaction?

According to my dr, post nasal drip can cause swollen lymph nodes because it's bringing down all the bacteria.

Amen. I told my ENT that my lymph nodes were swollen regularly and he immediately jumped to the conclusion that I may chronic fatigue symdrome. I suspect that it was because he didn't know how else to alleviate my sinus symptoms, which I believe are caused by allergies.
