Hello.I am having pain at my jaw area, immediately in front of my left ear. The pain is random. Is most painful when I m trying to chew but again, doesn t happen often. It s the kind of thing that if you are on an airplane & have ear pain and you try to yawn to pop your ears, if I try to do that, it feels like it ll get better but I can t achieve the pop that you d get on a flight. My feeling is it is somehow related to sinus but that s just a gut feeling. - thx
You are very astute to consider sinuses.  You likely have a Eustachian tube dysfunction.  The Eustachian tubes are located in between your ear and jaw and are responsible for regulating the pressure in your inner ear.  Sometimes from colds, allergies, or change in elevation, the Eustachian tubes get tight and fluid from the ear does not Chat Doctor.  This can easily be reversed using medication for sinuses such as antihistamines and nasal steroids.  If you still have the pain, consider getting seen to make sure the ears are looking okay on the inside.
