Ear Pain and Itching After Swimming? Swimmer's Ear (Otitis Externa) Alert

How can the concepts of damp-heat and wind evil from Donguibogam be understood in modern medicine? They map directly onto the mechanisms of otitis externa. Otitis externa refers to inflammation of the external auditory canal, the pathway leading from the outside of the ear to the tympanic membrane. It is commonly called swimmer's ear, reflecting its strong connection to water exposure. The damp-heat of Donguibogam corresponds to a warm and humid environment in modern medicine. The external auditory canal has a narrow, curved structure that easily retains moisture. When water entering after swimming does not dry, when there is heavy perspiration, or when someone is consistently exposed to a humid climate, the inside of the canal becomes moist and its temperature rises. This damp, warm setting provides ideal conditions for bacteria and fungi to proliferate. Furthermore, the skin of the canal is thin and sensitive, making it vulnerable to moisture, which can cause maceration and tissue breakdown. It functions much like how skin softens and weakens in humid summer weather. Wind evil corresponds to external bacterial infection or physical irritation. The primary pathogens in otitis externa are bacteria such as Pseudomonas aeruginosa and Staphylococcus aureus. These bacteria multiply quickly in warm, moist environments and trigger inflammation. In addition, frequently scratching the ear or creating micro-abrasions in the canal lining with cotton swabs or ear picks opens a pathway for wind evil. Even a tiny scratch allows bacteria to enter and cause inflammation. Allergic reactions or exposure to irritants like shampoo and hairspray can also inflame the canal skin. When otitis externa develops, ear pain is the most common symptom. It often starts as mild itching and progresses to a throbbing ache as inflammation advances. In severe cases, moving the jaw or pulling the ear causes intense pain. The canal swells, producing a clogged feeling, and hearing loss may occur. In more advanced stages, pus-like discharge may drain out. This inflammatory response occurs as our immune system defends against invading bacteria. If inflammation continues, surrounding tissues can be damaged, potentially progressing to otitis media or a deeper infection, so it should not be neglected. In conclusion, the damp-heat and wind evil described in Donguibogam align with modern medical science: a warm, humid environment (damp-heat) within the external auditory canal promotes bacterial infection (wind evil), resulting in inflammation (otitis externa). If your ear feels uncomfortable, pay attention to the signals your body is sending rather than brushing them aside.
