Hello
Thank you for posting your query at DoctorSpring.com
I can understand your concern.
You have fungal infection called tinea or ringworm. It's caused by a fungus called dermatophytoses. It's caused in conditions of heat and humidity.
I would recommend application of lamisil cream which contains terbinafine. Application twice a day would be required. Itching can be controlled by an anti histamine like claritin.
This will help resolve your lesion.
Please let me know if you have any queries.
Take care,
Regards.
