For me, it doesn't hurt too much today, granted I'm taking painkillers and antibiotics pretty much every other hour, and flushing my mouth with salt water and applying ice packs every four hours. The ice helps keep the swelling down, and the salt water cleans out blood clots and makes the sores shrink, thus speeding healing time.
As for the avatar and vid: The avatar looks pretty sweet, and I LOL'd at the video.
