The sensation of plugged ears can be unilateral (only right ear or only left ear), and it can be bi-lateral. the senstion may come and go for hours, days and weeks. The level of hearing is modified. The change may be in the quality of sounds, the ability to discriminate between words, or general hearing impairement.
