Thanks for writing in.
It does sound like a fungal infection
. There are several things you can do for this:
a. Apply Lotrimin
ointment on the affected area ( on the buttock cheeks and between the toes)
b. Have a bath twice daily, especially after you play/exercise/sweat
c. Keep the area clean and dry. Its important to dry the skin between your toes as well
d. For the itching, you can take Tablet Cetrizine
10 mg once daily for 1 week.
This should take 1-2 weeks to resolve. If it does not resolve, please see your physician.
