Thanks for writing to us.
Pain in the left jaw post surgery can be due to re-infection or inflammation associated with dislocation of jaws.
I would suggest you to get a thorough clinical evaluation as well as palpation of the affected area.
A radiographic examination of the involved area will help to rule out the cause of jaw pain
Analgesics along with muscle relaxants has to be administered.
If there is inflammation,antibiotics has to be administered.
Jaws has to be immobilised for a while.
Based on the diagnosis,treatment can be planned.
I hope this helps.
