I went to my ENT once with a horrid ear ache and thought it was a sinus infection, as I get them alot. Come to find out he said I had VERY dry ears due to the weather being so cold and the heat on too much..
I seriously had no idea that could happen. He also said many folks with TMJ have the same symptoms as folks with sinusitis.
Hopefully your under an ENT's care as they deal with this stuff all the time. Sure hope you get some results so you can get some relief.
Best wishes and keep us posted...JJ...
