Ear wax can quite often be removed without any prior treatment or preparation at all. Occasionally, however, ear wax can be difficult to remove if there is a large quantity of hard ear wax.
Hard ear wax can be softened with sodium bicarbonate eardrops. This can be obtained from most pharmacists and 3 to 4 drops applied 3 times a day for 2 to 3 day prior to the ear wax removal appointment.
Sometimes eardrops can cause the ear wax to expand blocking the ear canal further. Once the ear canal has been cleared this sensation of blockage will resolve. Some people can have sensitive ear canals, which may be irritated in particular by sodium bicarbonate eardrops. If so an alternative such as olive oil drops can be used.
