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.
Itchy ears are a very common problem. For some people the problem is so bad that they stick various objects into the ears, causing trauma to the ear canal.

Some people with allergies complain of Itchy ears. The ear canal may be normal on examination or there may be scaling of the skin. People aggravate the problem by using things such as bobby-pins, coat hangers and tooth picks to scratch the ear.
