Tinea pedis is the scientific name for tinea pedis, which is caused by a fungal infection and is somewhat contagious. If applying Dacrynic ointment does not work well, it is recommended to change to another ointment with a different mechanism of action. For example, terbinafine ointment can be applied twice a day and can be cured after 1-2 months of treatment. If the effect is still not good according to the course of application, it is recommended to go to the hospital dermatology department for relevant examination. It may be a lot of eczema or other allergic skin disease. If there is no fungus in the fungal examination, exclude tinea pedis. Eczema can be applied topically with mometasone furoate cream, compound flumethasone ointment applied twice a day, itching severe with oral levocetirizine tablets. The actual foot is usually not scalded with hot water or washed with soap.
