I’m 27 years old After giving birth toy son 7

Patient: I’m 27 years old. After giving birth toy son 7 years ago I began getting ingrown hairs/boils in my vaginal area. Very painful. I made an appt with my obgyn and she called it a skin disease and said factors included my being overweight and being a smoker. She gave me a prescription and it was almost $800. That’s how much I make biweekly. Is there anything I can buy at a pharmacy over the counter to help reduce this problem and help Rid myself of scarring? Please help, I’ve been very afraid to be sexually active for over 4 years becauseI afraid it will look as if I have an STI.
