I believe I have ringworm. I have a red circular patch?

I believe I have ringworm. I have a red circular patch that is scaly. Itchy at times. It has been noticeable for about 4 days. I have been in contact with children in Kenya who I am almost positive have tinea capitis. I have not had ringworm in the past. I am currently taking a daily dose of doxycycline 100mg po for preventative purposes for malaria.

Age: 28
Female
Medications: Doxycycline

Question: I have ringworm…used meds but it got worse

I have developed ringworm at the inner thigh near groin area.

I have applied few medicines but gave only temporary relief.. And the patch got increased.

After reading at various sites, I used fourderm cream which worked but left skin pigmentation and white patch near the area. I stopped using and switched to my regular cream clobet gm, the pigmentation has worsened and skin has become red at the white patches….

Can you please suggest a solution for the pigmentation and redness…FYI…I still have the itching effect for the ringworm.
