Jst got back from er for 2nd time to get jaw checked. came home and had 1 sneeze and now considerable pain after sneezing. how can 1 sneeze affect?

Jaw pain: The force of a sneeze and the jaw motion associated with it could easily flare up TMJ pain. You should be on a good TMJ regimen with NSAIDS for pain and inflammation. You should see a dentist who specializes in TMJ or see a craniofacial specialist for assessment of occlusion, possible physical therapy, possible night guard, and other modalities.
