“Tinea pedis, medically called tinea pedis, is a skin disease caused by a microorganism called “fungus” that infects the feet and has an incidence of about 25 percent. Currently, there are many misconceptions about the prevention and treatment of tinea pedis. One is that tinea pedis is a minor problem and it does not matter whether it is treated or not. The second is that tinea pedis is a manifestation of internal detoxification and that curing it will bring about other diseases. Third, they believe that ringworm cannot be cured and that recurrence is normal, and fourth, they believe that they can just buy an ointment from a drugstore and apply it. First of all, tinea pedis is the main source of infection for all ringworm diseases, and if left untreated, it can spread to other parts of the body or other family members, and can also cause bacterial infections of the feet or lower extremities, such as dermatophytosis; when the fungal infection of the feet worsens, it can also cause other parts of the body to suffer from a medical condition called “ringworm rash” because the body is allergic to the metabolites of the fungus. “The local itching caused by tinea pedis can also affect the patient’s work, study and rest. Secondly, there is no scientific basis for the idea that “ringworm is a manifestation of internal detoxification and that curing it will bring about other diseases”, and doctors hold a negative view. In addition, there are good antifungal drugs available in the clinic nowadays, and as long as they are used correctly and in sufficient amounts, it is possible to cure tinea pedis completely. The first step in successfully treating tinea pedis is to properly diagnose it, and a fungal test must be done to confirm the diagnosis. Clinically, it must also be distinguished from a variety of diseases such as eczema, sweat pimples, and palmoplantar pustulosis, which are commonly found on the feet. A combination of oral medication and topical antifungal creams is the best way to completely cure tinea pedis. The temperature is rising rapidly and the summer is about to enter a hot and humid period, which is a time of high fungal reproduction and high incidence of tinea pedis.
