When the symptoms of corns are mild, they can be treated with medication. Commonly applied medications in clinical practice include cornsore cream and salicylic acid ointment. Certain Chinese herbs, such as crow’s nest, can also be used to treat corns. The specific medication needs to be based on the individual situation and the doctor’s diagnosis, and should not be used without authorization. Medication generally uses the corrosive nature of the medication to erode away the tissue muscle in the area of the corns, thus causing the corns to fall off. Regardless of the brand of corns, the main ingredient is generally salicylic acid, which is strongly corrosive and needs to be used under the guidance of a doctor. In order to achieve a more pronounced treatment effect, the corns are usually cleaned and soaked before using the cream to soften and remove the corneal layer, and then the cream is applied to the corns. Generally 7-10 days to replace a corns eye cream, each time the replacement of corns eye cream should clean, deal with residual material, and then replace the dressing. If the condition of corns worsens, causing strong pain, affecting walking function, or bleeding or pus, you should not continue to use the corns ointment at this time. After the inflammation and bleeding at the corns have improved, you should go to the hospital for physical therapy or surgery to remove the corns as soon as possible.
