If you are worried about the pain, go back and get it checked. The post removal care is included in the cost of the extraction, so you shouldn't have to pay, and they should keep seeing you until its all sorted. I had a major surgical removal where the surgeon had to take some bone out and that hurt like jimminy for at least a week, but a garden variety removal you should be noticing the improvement. FWIW the specialists I saw recommended Panadol + nurofen as the most effective dental pain coverage, if that's not working them that's a good sign you should get it checked out.

Hope you're feeling better soon.
