Hello and Welcome to ‘Ask A Doctor’ service.
I have reviewed your query and here is my advice.
Well, I have read your complete explanation and the
stiffness in jaw, ear pressure and neck tightness is all appearing to me related to muscles but the point of origin seems to be jaw joint.
As you mentioned that the pain and stiffness increases when you are stressed and also the
dentist mentioned teeth grinding, therefore teeth grinding or
bruxism and teeth clenching can be a cause.
So my suggestion is to get an x ray of the jaw joints that is a Panoromic x ray done so that the exact cause can be ruled out..
Also you can get the
ultrasound done for further diagnosis.
However it looks related to the jaw joints only.
So for now you can take muscle relaxants like Chlorzoxasone and also do alternate warm and cool compresses.
Do
meditation and deep breathing exercises so that the stress is minimized and the bruxism and clenching reduces.
Take soft meals and avoid excess mouth opening.
Continue massaging the muscles in round gentle movements of finger tips..
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. Honey Arora
