I recently had a broken molar repaired with filling material as opposed to a cap. Two injections were administered for the Anaesthetic. I have had a fair amount of dental work in the past but I noticed that the pain after was far greater than before. I took ibruprofen for a full 7 days after. The pain seemed to subside. A few weeks later and now I have a large sore lump at the site of the injections. I am concerned as to what it could be. I am a 42 yr olds male smoker
