Otitis externa is an infection, inflammation, or irritation of the ear canal, the tube leading from the outer ear to the eardrum. Because it is often found in swimmers, particularly in warm, humid climates, it is often referred to as swimmer’s ear . This condition can easily be treated but can become serious, even life-threatening in some people, if left untreated. This can be very serious particularly in diabetics , where the infection can spread to the middle and inner ears, and cause an infection in the bone ( osteomyelitis ), described as malignant otitis externa. Contact your doctor if you think you may have otitis externa.
