I just got mine out a few weeks ago. I couldn't eat solid food for just over a week b/c my jaw was so stiff from swelling I couldn't openit to eat anything other then that on a spoon. However, It took a full 2 weeks to get rid of the pain completly, and it still hurts just a bit if I put pressure on it or talk to much. But all 4 got taken out, and were impacted. Plus, keep in mind, while the pain may be gone, it takes about a month for the gums to completly heal up, so keep them real clean, and brush your teeth!
Oh, and one more thing, it's the 2-3rd day after that hurts the worst, especially if they were impacted. No lie. They told me this, and I thought I was fine so went out to the bar, the next morning my whole face was swollen and I was in so much pain! I had to start making sure I took the pain meds RIGHT before going to bed or every morning I had a painful awakening.
