1. When corns occur in the early stage, it is only local hard skin hyperplasia. At this time, if you deal with them early, you can avoid the formation of subcutaneous lumps. Of course, the first thing is to replace those shoes that make you uncomfortable to wear. The second thing is to soak your feet in warm water every night for about ten minutes, and then use pumice to grind off the thick cocoon. When using pumice, you should also pay attention to it. Don't use too much force to cause skin damage and grind it off. 2. If the thickened cocoon is deep, pumice can't be used for surface treatment, but it won't hurt or affect walking. At this time, although many people will choose to buy corn patch, ointment, or some salicylic acid products sold in the market, these products usually have the function of acidic cutin dissolution, so special attention should be paid to the use, and it is best to use drugs under the instruction of a doctor to avoid skin burns or ulcers caused by improper use. Of course, the best way is to directly consult a doctor in the dermatology clinic, and the doctor may give gradual drug treatment according to the situation at that time. 3. If the corns have penetrated deep into the bottom layer of the skin, when pressing, it can be found that lumps have been formed, and then there is pain when walking, so it can't be delayed, and it must be removed by surgery. This small operation only needs local anesthesia, and the corns can be removed from the roots. You can recover in about a week. Never use scissors to cut off the epidermis yourself, because this action is too dangerous, which will not only form wounds but also cause infections, and there is still no way to eradicate corns, especially for diabetics who already have terminal blood circulation problems. If any wound on their feet is not handled properly, it may lead to the fate of limbs.
