Otitis externa is a term used for inflammation in the ear when it is confined to the ear canal and does not go further than the eardrum. If you get things like water, shampoo or soap in your ear then it can cause itching. If you then scratch or poke your ear, this can damage the skin in the ear canal and cause inflammation. Sometimes the inflamed skin becomes infected by germs such as bacteria or fungi. Clotrimazole solution is used to treat ear infections caused by fungi. It is available on prescription or you can buy it without a prescription at a pharmacy.
