Swollen Lymph Node

I woke up this morning with a swollen lymph node on the left side of my neck. I feel it, and you can only see it when I turn my head a certain way.

I’m not ill, but my allergies have been flaring up. I also had an extensive root canal on Monday on that left side...not sure if that would have anything to do with it.

I don’t truly believe it is serious, just looking for some input.

Anyone else have this?

Could just mean your body is fighting something off. You don't even necessarily have to feel sick.
