Question

What is the reason behind the cause of ear pain while climbing a mountain? How it can be rectified?

Answer 1

• When one ascends a mountain in a plain, the external pressure drops while the pressure within the air cavities remains the same. 
• This creates an imbalance. The greater internal pressure forces the eardrum to bulge outward causing pain. 
• With time and with the help of a yawn or two, the excess air within your ear’s cavities escapes thereby equalizing the internal and external pressure and relieving the pain.
