When a patient comes to the clinic, the first thing to do is to check the itchy area for papules, blisters, and flakes, and if so, scrape some flakes locally for a fungal test. If no fungus is found, the diagnosis is eczema, and topical dermatoprost ointment and zinc oxide borate ointment can be used. If nothing is seen in the location of the itchy toe and it is the same as normal skin, the itchy toe is usually considered to be caused by poor ventilation due to dampness and heat, so you can take oral medications such as anti-ginseng and anti-itch granules and moistening and anti-itch capsules.
