Suggest Treatment For Burning Sensation In Vagina And Labia

I am a 63 year old woman with diabetes, insulin dependent. I have been celebrate for 15 years. Four years ago I was Dx with HPV and had a LEEP procedure. Following a 2 week bout of asthma I began experiencing a burning sensation in my vaginia and labia. I took 3 days of Monostat with no relief. What should I do?
