Thanks for your feedback. Would you say this could be a Tension Headache? As that is what my doctors are saying.
A Eustachian tube to connects the throat to each middle ear, allowing air pressure to equalize around the sensitive timpanic membrane (eardrum). Eardrums and Eustachian tubes are common to some reptiles, birds, mammals.
My best guess is that you are experiencing Eustachian tube dysfunction due infection, allergy, or other problem, which is preventing equalization pressure on the eardrum.
This can cause sharp pains in the head -- level 10 pain -- that no pain reliever can eliminate.
Scuba divers, airline pilots, and others who are subject to pressure changes call this condition 'squeeze'. If untreated, it can rupture the eardrum.
It seems that everything has a website today. Here's an interesting article about this problem where you'll find plenty of information about causes and treatments:
