I had a crown prep and a root canal during the last two weeks.  When the dentist gave me a novocain shot I felt a huge shock.  I have had pain in my jaw ever since.  I feel it in my ear, below my ear, in my chin.  Is this from the shot?  When will it go away?  Its been a week now.  The pain is less but its still driving me crazy.
Thanks for your query, I have gone through your query. The pain can be because of the injection. While injecting the Novocaine, the trauma cause at the site of injection, the muscle fibers or nerve can result in pain. Usually it will go after a week to 10 days. Nothing to be panic, take a painkiller, do saline gargling 3-4times daily. If the pain does not subside, then consult an oral physician to rule out other causes of pain below the ear like TMJ disorders. I hope my answer will help you, take care.
