How did you feel 2 days after wisdom teeth extraction?!

I had 4 wisdom teeth pulled friday morning, it's now Sunday evening. The 2 bottom teeth were impacted, my left bottom one had small infection and right bottom one was inverted and buried in bone. I had laughing gas and the regular shots, I felt the last one (bottom right) when he tried to drill it out. He stopped and gave me more shots.
Now my face is massively swollen, and I can hardly open my mouth. I used ice packs the first 24 hours, and now I am trying heat. I have been rinsing every few hours with warm salt water, eating jello, pudding, soup...however my lower lip and part of my chin are still swollen. And when I look in my mouth I see this white/yellow spongy stuff around my bottom left tooth, and it goes on the side of my cheek too! It wont rinse out, and it looks gross!! I am taking penicillin and vicodin, and not using straws. What is that white/yellow stuff?? When did you feel better after getting teeth out? When did you eat a hamburger or steak? Please help!!!!!
