What is a common treatment for an ear block caused by altitude changes?

Consulting a flight surgeon is the most appropriate response for managing an ear block caused by altitude changes. An ear block, or barotrauma, typically occurs when there is a pressure differential between the middle ear and the external environment due to altitude fluctuations. A flight surgeon possesses the specialized knowledge and training to assess the severity of the condition, recommend proper treatment, and ensure that it doesn't interfere with flying safety. They can provide guidance on how to safely equalize ear pressure or determine if further medical intervention is necessary.

In contrast, while taking deep breaths may provide temporary relief for some individuals by promoting relaxation, it does not address the underlying issue of pressure imbalance in the ear. Rapidly increasing altitude is counterproductive, as it can exacerbate the ear block and associated discomfort. Using earplugs might help to some extent by dampening the sound and pressure changes, but it does not facilitate the necessary equalization of pressure within the ear. Therefore, consulting a flight surgeon is the most reliable and medically sound course of action when experiencing an ear block related to altitude changes.
