I Am Diagnosed With Fungal Infection On My Buttock And

I am diagnosed with fungal infection on my buttock and groin area and Atypical Pityriasis Rosea on my trunk, chest, back, neck, arms and thighs. Doctor prescribed me Wysolone and diprovate plus lotion for Atypical PR and terbicip cream for my groin and buttock area. Marks are lighter as compared to the marks I was having at the start but there is no change since last week. What can I do ? Is it safe to wax during this time ?
