There is a rash at the root of the thigh. What's the disease?

If accompanied by local desquamation, erosion, tingling and itching, it may belong to tinea cruris caused by fungal infection.

Wear loose cotton underwear and don't eat spicy food. Fungi like warm and humid environment, so tinea cruris may recur after treatment, but as long as we keep local dryness and don't touch the source of infection, it is rarely recurrent.

Patients should take isolation measures as far as possible after illness, and do not mix their clothes and daily necessities with their families. Change underwear frequently, take a bath frequently, and disinfect bedding in time. Try to avoid sexual relations during illness.

Of course, you need to pay attention to a light diet, eat more fruits and vegetables, and prohibit spicy food. Is it suitable for external use?
