So I have a swollen lymph node (I’m assuming) about the size of a blueberry in my armpit. I just noticed it today, but I’m a tiny bit worried. I do have a sinus infection coming on so I was reading that could affect it, but I was also reading that you should wait 10-14 days from when you see it to see a doctor?

Idk... should I wait 1-2 weeks or see a doctor now? It’s hard, but doesn’t hurt.
