Severe jaw joint pain started 24 hours ago, right side. pain when opening mouth and clenching. should i go to the er? worse as day went on. tmj?

Jaw pain: Would f/u with doc /urgent care/ ER today could be TMJ especially with clenching, could also be retrophyanrgeal abscess ( may not be painful), oromandibular dystonia, trismus or tooth/parotid abscess ( should be painful), rarely tetanus.. if you grind or clench would get a mouth guard when sleeping.if you have difficult swallowing secretions ,eating or talking go to ER as son as possible.

TMJ: Sounds like TMJ. Going to ER not very useful. They will give pain meds and tell you to see a dentist. See an oral surgeon. If TMJ, ask for referral to TMJ expert.

Probably TMJ: ER will only give you pain meds, not treat the cause of your joint dysfunction. Please call your Dentist for immediate relief.

Likely TMJ disorder: see your dentist asap fro proper diagnosis and therapy.
