Patients with itchy, swollen and painful ears can be treated clinically according to the degree of itching, swelling and pain in the ears. If the itching, swelling and pain of the ear are mild and the local skin temperature is not significantly elevated, you can apply topical Bactrim ointment or Ruyi Gold ointment to promote faster relief of the local itching, swelling and pain and faster healing of the wound without causing serious infection. Second, if the symptoms of itching, swelling and pain in the ear are heavier, and the local skin temperature increases significantly, and even a small abscess is formed locally, and the itching, swelling and pain do not improve significantly by applying topical drugs, oral amoxicillin and cephalexin can be given to strengthen anti-infection treatment. For those with local abscess formation, abscess incision and drainage should be carried out and the wound surface should be changed and cleaned, so that the symptoms of local itching, swelling and pain can be solved more quickly.
