3. Feeling of congestion in the ears
Congestion in the ear may not be a sign of an infection but can be a symptom. Other things can cause congestion in the ear besides an infection.
This can be caused by irritation of the upper respiratory system or flying in an aircraft. It is important to get your ears checked if the congestion persists for more than a couple of days, and becomes more severe rather than less.
Another possibility is a buildup in the ear or foreign objects.
