Ears can be blocked in a number of different ways. The external ear canal can be blocked with earwax or a small foreign object. These types of blocks can cause hearing difficulty and discomfort, and must be removed. Q-tips should never be used to remove earwax from your ear canal. Another type of blockage in the ear can occur in the middle ear, which is most often caused by an ear infection and fluid. So yes it could be due to water agrrevating the ear if you have an infection or sinusitis. In both cases it is important to see an ENT who will diagnose the problem and prescribe the correct treatment.
