Yeast infections

Chloe
Okay, so this is absolutely the worst yeast infection I've ever had. I'm not sexually active and I have great hygiene. It started with itching and burning down there and then I started to have a lot of discharge. I went to the doctor and they prescribed me Diflucan for it but it hasn't cleared up or stopped itching. It honestly itches everywhere on my lady parts. I've also tried monistat but it won't let up. The itching gets worse after I urinate. Help please????
