Is this something to be concerned about? I've had a swollen lymph node under my right jaw for several weeks. I've had my doc feel it a couple of times, and when she noticed it getting bigger, she put me on a round of antibiotics (Keflex) which she said should clear it up.

I'm only about 1/2 way through the antibiotics... but it's not getting any better. I have no symptoms of anything. No fever, pain, etc. Just worried about this swollen lymph node. Should I be worried?

The doc told me should would probably send me to an ENT after the antibiotics, if they don't work.

Any thoughts?
