Patients who drink a lot of alcohol can lead to a decrease in resistance and may get infected by bacteria and viruses, which can lead to inflammation of the ear or congestion of the eardrum and pain in the ear. In terms of treatment, patients are advised to have their ears examined at a hospital. If it is determined to be caused by inflammation, you can use levofloxacin ear drops in the ear for anti-inflammatory purposes, and the condition should improve in about 2-3 days. In another case, consider that a boil may have formed in the patient’s ear canal, which the patient may not have been concerned about. After drinking alcohol, the boil in the ear worsens, so pain can occur. It is recommended that fusidic acid cream or denuded cream can be applied to the ear canal, which can also effectively reduce inflammation and swelling, and the condition will definitely improve after active treatment.
