Itchy and painful feelings inside the ear are often caused by the condition of eczema in the ear canal, and eczema may be accompanied by an acute attack of inflammation of the external ear canal. The occurrence of eczema in the external ear canal is often related to the surrounding air environment, high temperature and humidity, and may also be related to repeated water ingress in the ear or repeated irritation of the skin in the ear by tears and sweat, which can easily lead to congestion, erosion, crusting and oozing of the skin of the external ear canal, causing repeated itching. This itchy symptom, in turn, can easily lead to repeated ear digging, which may further cause acute inflammation in the external ear canal, resulting in local swelling and pain, requiring the use of antibiotics and active anti-infection treatment.
