I think i might have ringworm on my cheek. i have been using anti fungal cream with clotrimazole for about a week, but there's signs of no improvement and it might have even got worse. it is redder and itchier. is there anything i should do?

You've diagnosed yourself and are using a medication that may not be effective against your condition. See a dermatologist for a definitive diagnosis of your skin condition. Only then can the appropriate treatment be rendered.

Failure of a good treatment likely means the label for the condition is wrong. There are several skin issues that can mimic the fungal problem. An in person visit may be required to sort out the true cause and available treatments.
