Ear itching is a tickling, irritating sensation accompanied by the persistent need to scratch your ear. Redness, swelling, soreness, flaking and scarring may occur in the area of itchiness. The medical term for itchiness is pruritus. Although scratching may temporarily relieve your symptoms, it can cause more irritation or lead to an infection. With most cases of itching, it is best to refrain from scratching and leave the area alone to heal. Itching can be a symptom of ear infection. A common ear infection is otitis externa, commonly known as swimmerâs ear, which can occur when moisture remains in the ear after swimming or other exposure to water. Other possible causes of ear itching include insect bites, contact allergies, and trauma.
In most of these cases, the itch is also accompanied by watery and irritated eyes. Occasionally, irritation as well as itching of the ear canals can be cause by sensitivity to certain shampoo or hairsprays. Another one of the causes of ear canal itching is also the insufficient development of wax of the ear. This is a very common condition in swimmers. But, even an excessive production or buildup of wax of the ear can cause the ear canal to itch.
