What Does Sharp Pain In The Ears Indicate?

Brief, sharp, intermittent infrequent ear pain. Sometimes left, right, or both. No fullness, no hearing issues, no tinn, no popping. No pain overnight. One Dr. (general practitioner) says reflux due to history with mild LPR symptom (light throat clearing after dinner). One Dr. (ENT) says TMJ. Neither Dr. looked to far into it, as I was in offices for other issues (yearly check up and throat clearing). Pain feels like right inside ear. Occasional pain when i push right under ear. No jaw symptoms. I m on no meds. I have no ear infection. Tylenol may help, but sometimes I don t think it does. PPIs didn t help (for about 2 weeks). Began chewing gum a few months ago, this MAY have aggravated it. I quit a month ago, no improvement. I have not tried all soft foods yet. TMJ or ETD?
