I had my wisdom teeth removed yesterday and I was put under general anesthesia. I was expecting a swollen mouth, and the pain, and all that. But when I saw myself in the mirror I noticed the corner of my mouth was bruised and bloody. I thought it was dry blood, but it's not. It's looks like my veins popped from maybe pulling my cheek for so long, but I don't think this is normal. It was my right upper and lower wisdom teeth that were removed, and my friend had this same procedure done but her cheeks didn't look bruised. Is this normal?

God, that's gotta hurt.
Keep chapstick on to keep your lips moist, it'll help the healing. And it never hurts to call and ask the oral surgeon.
Luckily it all heals quickly, mine did within 2 weeks. Give it another few days before you stress.
