For 2 months my left jaw under my ear hurts when I bite down more in the morning and lets up during the day.
It could just be that you are grinding your teeth at night, when you are at the dentist you can have him/her check you bite. Or it could be more serious TMJ which is the joint between the mandible (lower jaw) which is the mobile part and the maxilla ( top jaw) the fixed inmobile part of the jaw. Again gringing teeth during sllep can cause this, being hit in the jaw, or even stomach sleeping where the jaw is out of aliagnment or shifted to one side for 8 to 10 hours, stress is a big factor these all can cause the tempomandibular joint to flair and cause facial and ear pain, as well as difficulty chewing because the ligaments are flaired. If you think any of these thing might be the cause try to change the habits and take anti-inflammatories to reduce swelling and you may want to see a dentist because they can better diagnois both TMJ and or Gringing which can be an easy fix (sleeping with a nightguard to prevent furthur damage to the ligaments)
Or it can be even more serious I have facial and ear pain associated with RSD/CRPS but did not show up until later up to one year of my DX. And only flairs up during really stressful times. And I am allergic to anti-inflammatories and on so many other meds ~ Fentanyl patch, Soma, Topamax, a Tens unit to try and help with pain and sleep and many more for major depression since dealing with chronic daily pain for 6 years now. I am still her, following one very serious suicide attempt, and trying very hard to cope.
I hope this is of some help!!! I am a dental hygienist ~ Hope you feel better soon!!
Thank you for your response but what is RSD/CRPS ?
