Wax production varies from ear to ear, and the shape of each ear canal can be slightly different. It's very common to find one ear completely clear while the other contains a significant build-up of wax.

If your ear feels blocked, muffled or "full", it's easy to assume ear wax is the cause. In many cases it is. However, sometimes people book an ear assessment expecting a large wax blockage, only to find there is very little wax present.
