If the patient has inflammation of the external ear canal, the pain in the ear canal will be especially obvious, and sometimes it will also be associated with headache, so it must be actively anti-inflammatory. In clinical practice, cephalosporin antibiotics such as cefprozil capsules or cefdinir capsules can be taken orally. It is necessary to clarify whether there is any history of allergy to cephalosporin antibiotics before using them to avoid allergic reactions. At the same time, you can use levofloxacin hydrochloride ear drops in the ear canal for local anti-inflammation or lomefloxacin ear drops for anti-inflammation. For ear pain or unbearable head pain, you can take oral loxoprofen sodium tablets or ibuprofen capsules for pain relief treatment. Normally, active treatment for a week or so will result in significant improvement. If you do not see improvement, it is best to go to the hospital for careful examination, and if necessary, you can improve the CT of the head or CT of the middle ear to clarify the diagnosis.
