??Lymph node or bruise/ pulled muscle?

So I noticed earlier today when my pants would rub against here it would sort of hurt. At first I thought it was just from sitting the way I was. But I just noticed , as I’m now wearing shorts, that when I press there it hurts..? Should I be worried? Could it just be bruised ? I’m freaking out a bit that it’s a lymph node and something is wrong with me.. is this where a Lymph node is located?

I don’t see or feel any swelling
