Suffer a bit o' pain & tinnitus in my right ear/jaw. Related? Not sure. Probably.
Think it all comes down to the Temporomandibular joint (TMJ). All started about 2 years ago when i got some fillings, had my ears belted at a concert, was stressing (clenching), sat a desk all day with bad posture, and was using hard silicone ear plugs when out and about (aggrevating it?)..
I'm thinking it was the fillings which may have shifted my jaw alignment and thus kinked things out near my heary-bits.
Am also thinking of cutting down my beloved coffee to see if that may reduce my clenching tendencies. Gah!
