Hi. If it has been surely diagnosed as a fungal infection, one needs to take a proper course of oral and topical antifungals. Stop using candiderma plus cream as it contains a steroid which can lead to side effects upon such long term use. Measures such as maintain proper hygiene, keeping areas dry, avoiding tight fitting clothing, etc . Can also help. U ideally need to see a dermatologist and hence take proper treatment.
