For the past couple of years I have had, for lack of a better medical term, itchy ear. I thought it was due to wax buildup but even after having my ears cleaned the itch persists, When I had my ears cleaned I mentioned this problem and was given (sold) assorted creams to apply, none of which were very effective although they did help. It isn't painful, just a bit irritating, and I suspect that the continuous itching could cause other problems later on. Does anyone else have this problem and if so how do you deal with it?

Itching is mostly a symptom of inadequate lubrication of the canal by ear wax. This can occur as a result of over-aggressive cleaning with earbuds over time or exposure to swimming pool water chemicals etc.

Ear wax is a natural barrier to infection so absence may make you more prone to this; can be limited by using proper ear plugs when swimming etc.
