In life, if a patient has pain in the bone next to the ear, two main conditions are considered: 1. The cartilage of the ear screen in front of the ear is likely to be inflamed, usually due to a boil that may have grown on top of the cartilage of the ear screen, often induced by fire. In terms of treatment, localized Bactrim cream can be applied to reduce inflammation and avoid repeated touching. 2. Patients with painful conditions in the mastoid bone behind the ear are often considered to have formed otitis media. In terms of treatment, it is recommended that patients take cefdinir dispersible tablets orally. It is necessary to clarify the allergy history before using the medicine to avoid allergic reactions. It is best to take a CT of the mastoid process to clarify the specific severity, and if necessary, anti-inflammatory antibiotics can be administered intravenously, and the patient’s symptoms should improve significantly after active symptomatic treatment.
