Otitis externa
Infection of the skin covering the outer ear canal that leads in to the ear drum, usually due to bacteria such as streptococcus, staphylococcus, or pseudomonas. Swimmer’s ear is usually caused by excessive water exposure.

Next the ear canal swells, ear drainage follows, and the ear is very painful, especially with movement of the outside portion of the ear.

A hearing aid should be left out as much as possible until swelling and discharge stops. The most common treatment consists of antibiotic ear drops (Cortisporin, Volsol, Cipro) with or without an oral
