Time is more meaningful today than many other days. Every 30 minutes I need to alternate icing my face and giving it a break... and let me tell you, the 30 minutes without ice are torture. Every 4 hours I can take more pain medication. Every 6 hours I need to take more of the antibiotic. If you've had your wisdom teeth out, you understand. If you haven't... trust me, you don't want to unless they hurt in the first place.
