The lymph nodes on the back of my neck seem to swell and hurt when my allergies flare up. Could allergies cause this and how can I relieve it?

Inflammation: Lymph nodes react to inflammation at times by swelling and tenderness. As long as they recede this is a benign situation. It's probable that inflammation of the nose and throat during allergic reactions are causing this in your case.

They ALWAYS do that: I'm glad you're health conscious. That's what lymph nodes are supposed to do. Everybody has a few palpable ones that come and go. They're your friends, fighting goodness-knows-what so you never know it attacked. Relax and be thankful for good health. ...Read more
