Small amounts of wax are made all the time and form a protective coating for the skin in the ear canal.  The amount of wax produced varies greatly between individuals.  In some people plugs of ear wax can form.  A plug of ear wax is not a serious problem though it may cause a feeling of fullness in the ear, can reduce hearing, may itch or cause discomfort.  If this is the case a nurse or doctor can examine the ear to confirm that there is wax insitu and ear syringing can be planned.  An appointment should be booked allowing 5 days of applying ear drops.  Ear drops such as sodium bicarbonate can be bought from the pharmacy and should be applied for 5 days.  Often drops alone clear the wax though syringing may be needed.  Ear syringing may not be advised in some circumstances.
