For example, some people often like to use cotton swabs to dig their ears, and repeatedly stimulate the mucous membrane of the ear canal, which is particularly prone to infection. The painful symptoms will improve or even heal, which means that the congestion of the mucosa of the ear canal can heal itself. It is recommended to keep the ear canal clean and free of water during the period of ear pain. It is good to observe if the pain gradually decreases, but if the pain gradually increases, it is necessary to use levofloxacin ear drops for anti-inflammatory purposes, and if necessary, go to the hospital.
