Those are all good signs. the cancerous nodes are. Big, continue getting bigger, are not movable at all and are rock hard they are also painless.
You're OK. I just got over a similar fear and what I was feeling weren't even exactly noses but in the process of touching them so much, I did make one swell. Don't touch them. It makes them way worse, seriously.
Some people also just have shitry nodes that are hard immovable etc but aren't huge. They never go away and sometimes ppl have multiple of them.
