I Have A Terrible Vaginal Itch And Burning I've Developed

I have a terrible vaginal itch and burning I've developed in last few days. I had a bladder infection last week and just finished a scrip for seven days of Cipro. I got some Vagisil wipes and cream this morning but it doesn't seem to help and kinda burns when I use it. Can I use Benadryl cream instead even tho I've taken a (one) Benadryl tablet tonite! Thank you,
