The causes of cracked heels include climatic factors, physiological factors, dry syndrome, athlete’s foot, etc. Treatment includes medication. 1. Climatic factors: If the cracked heel is caused by the cold and dry weather, you can give enough warmth to the treatment. 2. Physiological factors: As the skin moisture content decreases due to ageing, so the skin cracks, at this time you can give moisturizing treatment, such as applying foot cream. 3. Dry Syndrome: If the skin cracking is caused by dry syndrome, then drugs such as cyclosporine can be given to inhibit immunotherapy. 4. Tinea pedis: If the cracking of the skin is caused by fungal infection of the feet, then you need to follow the doctor’s instructions to give drugs such as oxiconazole and luliconazole for antifungal treatment. The above are only some of the common causes. If you have cracked heels, please consult your doctor for a clear diagnosis and standardized treatment. The use of drugs must follow the doctor’s instructions, not blindly use their own drugs, so as not to cause adverse consequences.
