The main symptoms of ringworm are skin damage (pimples, erythema, flaking) and conscious itching. Ringworm is a skin lesion in the groin, buttocks, and perineum caused by a fungal infection. 1. Skin lesions: red papules and blisters appear at the beginning, and then gradually merge into red patches with scales and clear boundaries, with the edges expanding to the surrounding area and the central area sunken, forming a ring of red spots. 2. Conscious itching: accompanied by different degrees of itching symptoms, may be due to itching caused by local scratching stimulation, causing local eczema-like changes, or moss-like changes. Suffering from ringworm, should go to the regular hospital dermatology diagnosis and treatment, pay attention to personal hygiene, follow the doctor’s prescription medication.
