Hey, I'm wondering how long it normally takes for a swollen lymph node to go away? I got a weird flu a couple weeks ago, and my lymph node in the right of my neck got swollen and tender. The flu went away on Friday, but the lymph node's still swollen and tender. It hurts a bit when I yawn, and it's getting annoying. It's been swollen for almost three weeks now. What do you think?
