Q. I had my wisdom teeth removed 4 years ago. Shortly after, and ever since, I have experienced pain and swelling on my left lower side in the exact area where the wisdom tooth was. I went to the dentist and he did x-rays to m,ake sure all of the tooth was removed and found that everything looked fine. Four years later I am still experiencing swelling and pain in that one area about once a month that lasts for a couple days.,
