Final answer:
When you experience discomfort in your ears upon descending, it is likely due to a change in air pressure. To relieve the discomfort, try swallowing, yawning, or chewing gum to help equalize the pressure. The Valsalva maneuver can also be helpful.
Step-by-step explanation:
If you experience discomfort in your ears upon descending, it is likely due to a change in air pressure. When you descend in an airplane or dive underwater, the pressure on your ears increases. This can cause a feeling of fullness or discomfort in the ears. To relieve the discomfort, you can try swallowing, yawning, or chewing gum to help equalize the pressure in your ears. You can also try the Valsalva maneuver, which involves gently blowing out with your nose and mouth closed, to help equalize the pressure.
