Does this mouth pain I'm having sound like something that is wisdom tooth related?

So I’m 21 and still have both my wisdom teeth (I only have them on the top, none on the bottom). Neither of them have come in yet and I’ve had no pain so far related to them. 2 days ago I noticed I was getting a pressured feeling on the left top side of my mouth, causing a tiny bit of jaw pain as well. It’s in the back of my mouth and my back 2 teeth “hurt” when I push on them with my bottom teeth. I use quotation marks because it’s not really painful, it’s just that I can feel it….I don’t know how to explain it. Anyhow, I have had MANY serious toothaches in my time and I know what a toothache feels like…this is not a toothache like any I have had. It doesn’t HURT….it just feels pressured. And when I open my jaw wide or yawn, I feel a bit of pain then.

I’m going to make a dentist appointment, but I know that my dentist isn’t open tomorrow and then I fly home on the 5th so who knows when I’ll actually get there. And I don’t think it’s an “emergency” so…..

Anyhow, for the time being, thoughts? Experience?
