Pustules inside the ear are usually external auditory canal boils, which can be treated with medication or surgery depending on the specific condition. External auditory canal boils are caused by staphylococcal infections, and can be triggered when people dig their ears and damage the skin of the external auditory canal, or when swimming water enters the ear. After the onset of the disease, the patient will experience pain in the ear, hearing loss, itching in the ear, etc. The pain will be aggravated when the patient opens his mouth or chews, and in addition, pustules can be observed in the ear, and pus-like secretions can flow out of the ear when the pustules rupture. When the boil is immature, patients can follow the doctor’s instructions to apply local ichthyol glycerin, ichthyol cream, etc., to promote the absorption of inflammation, but also combined with hot compresses, microwave therapy, etc., to control the condition, and in severe cases, the use of antibiotics, such as penicillin, cephalosporin, azithromycin, etc., to control the infection. When the boil is mature, incision and drainage is feasible, and drainage strips are placed in the pus cavity. If boils on the external auditory canal are not treated in time or handled improperly, the inflammation may spread, and it is recommended that patients go to the hospital in time and follow the doctor’s instructions for standardized treatment.
