Otitis externa, or swimmer's ear, is a disorder in which the external ear canal becomes inflamed. Although other factors including dampness, damage to the ear canal, or allergic reactions might contribute to its development, bacterial or fungal infections are the usual cause. Otitis externa is a common condition, particularly in people who swim a lot or have a lot of moisture in their ears. Otitis externa can cause a variety of symptoms, but the most common ones include redness, itching, ear pain, swelling in the ear canal, and pus or fluid draining from the ear. When pressure is applied to the tragus, the little cartilaginous projection in front of the ear canal, or when the outer ear is moved, these symptoms may get worse. In extreme situations, people may feel as though their affected ear is fuller or lose their ability to hear. The usual course of treatment for otitis externa is to treat the underlying infection and reduce symptoms. To eradicate the causing organism and lessen inflammation, this may involve using ear drops treated with antibiotics or antifungals. It could be advised to use painkillers like ibuprofen or acetaminophen to manage discomfort. Oral antibiotics or antifungal drugs may be required in certain situations, particularly if the illness is severe or recurrent. Reducing the risk of infection and minimizing moisture in the ear canal are important stages in the prevention of otitis externa. This can involve using earplugs or a swim cap to protect the ears from water exposure, drying the ears completely after swimming or taking a bath, and refraining from using cotton swabs or other items that could harm the sensitive skin of the ear canal. To keep the environment in the ear canal dry, those with a history of recurrent otitis externa might find it helpful to use over-the-counter ear drops that include acetic acid or alcohol. In conclusion, bacterial or fungal infections are frequently the cause of otitis externa, a common ailment marked by inflammation of the external ear canal. Ear pain, itching, redness, and swelling of the ear canal are some of the symptoms. To treat the infection and reduce symptoms, ear drops containing antibiotics or antifungals are usually used.
