Honestly, do I need to go see a Dr?

For years I’ve had stuffy noses. It’s been common for me. I just figured I was a nasally person from not being super active physically. I’m 27M. I have also been diagnosed with multiple ear infections when I was younger. Many many ear infections. However for the past week I have discovered a hard lump on the back of my neck, left side. It’s not SUPER hard, it’s sort of rubbery but still hard enough. It’s not super massive. I went to a wellnow, about a week ago and they told me it was cellulitis/W swollen node. I thought “huh; weird” but maybe if I take these antibiotics it will go away. However the rest of my symptoms are strange. Ear popping, constant nasal congestion. DRY throat. Globus sensation in my throat like a rock was stuck in there. And my voice seems to be sort of hoarse, and not usually what it is. I am getting concerned, because I read up on nasopharyngeal cancer, and a lot of these symptoms are what I’m currently experiencing. Maybe I shouldn’t continue to put this off.
