Patient's question:
I have an itchy lower body, and my underwear is always yellow. What's going on? How is tinea corporis caused?Doctor's answer:
Tinea is primarily caused by fungal infections and can occur on any part of the body. It starts as scaly red plaques with clear borders, and the lesions develop rapidly with severe itching. Treatment mainly relies on topical antifungal medications. Due to the fungal infection, symptoms may recur easily after the medication is stopped. Therefore, the treatment course must be sufficient. Commonly used medications include Daktarin, Pekang Cream, and Desonide Ointment, which have minimal irritation. Treatment must be thorough, and after symptoms disappear, continue using the medication for about one week to prevent recurrence. Additionally, it is essential to maintain good hygiene.
