Sense of pressure in ear
Why is there a sense of pressure change inside the ear when someone goes down a mountain?
Expert

When someone goes down a mountain air pressure on the middle ear raises and it is essential to do some exercises like fake swallowing to force the opening of pharyngeal orifice of the auditory tube to equalize pressure again.
