Burning sensation that doesn’t go away

Hi. My vagina has been burning for 3 months now. It burns when I pee or have sex. I’ve been to many doctors many times. I got tested I don’t have a UTI. Doctors gave me medications for BV and yeast infection. It just doesn’t go away!

My burning started when I started taking birth control pills. Is it possible that’s causing this?? I’m taking desogen btw.

I’m just losing my mind here 😫

And yes, I’ve been tested for STI, STD, HPV,... everything.

But I just finished using clotrimazole vaginal cream. Could that be the cause of burning?
