Hi! I just got my wisdom teeth out 2 weeks ago today. It sucks that you didn't get any post op instructions. I wasn't told not to drink any hot liquids within 24 hours either. I had soup the night of the surgery, so I didn't follow that one I guess. I did rinse with salt water a lot for the first week. Have you been rinsing with salt water?
I didn't really have problems with food getting stuck. I don't really have holes back there. And I didn't eat much for the first week. I only ate stuff that I didn't have to chew and I'd swallow it whole. So nothing got stuck back there. If you try not to chew with your back teeth and rinse right after eating, stuff shouldnt get too stuck there. If food does get stuck, you can be at risk for infection. Were you put on an antibiotic? I had to stop mine after a couple days cause it made me sick to my stomach, so I had to be extra careful about infection.
As for the pain, I know how you feel. I had to stop taking my percosets because they made me sick too. It wasn't sharp pain, but dull aching throbbing pain. I think that went away about 8 or 9 days after the surgery. That was about the time that I could open my jaw almost all the way and I could chew pretty well. I took advil or aleve for the pain. It's been 2 weeks, and I am almost completely better. My oral surgeon said I should be feeling fine by 2 weeks, and he was right. The aching is gone. The only problem is that by the end of the day or after I've eaten, I get a little pain at the very back of my jaw on the bottom right. It's nothing horrible, and I'm sure it will go away. And I'm sure that in a week or so you will be feeling good too.
Make sure to talk to your dr about food getting stuck or any other concerns when you go back in a couple days. Ask for some cleaning instructions since they didn't give them to you before. And the dr will be able to tell you if everything is healing ok.
