Ummm. Actually. Help.

Right. I'm a bit worried now. It's been just over a week since my operation and I still can't feel my chin or my bottom lip. You could pierce it and I wouldn't notice. Additionally, I woke up in the middle of the night in tears because my painkillers had worn off. And I slept pretty much solidly from midnight last night until about 5pm today. What. The hell. Is going on? Are there any doctors reading? Is this weird? I know I should actually just phone someone and ask but I'm a bit scared.
