You have clearly done everything in your power to fix the problem yourself. So we know this is not a lifestyle problem or anything you’re doing wrong.

My best guess would be that you have Trichomoniasis. You didn’t mention whether they tested you for it or not. If not then please do so. All of your symptoms fit with Trich. http://www.plannedparenthood.org/health-topics/stds-hiv-safer-sex/trichomoniasis-4282.htm#where

My second best guess would be that whatever it is it’s getting passed back and forth between you and your husband. He could have something but not have any symptoms. So just when you start to heal you have intercourse and the bacterial infection is passed back and forth. Abstain during treatments and possibly have him get tested.

What you DO have is Vaginitis. That’s the general term for what you’re experiencing regardless of the actual cause. Here is information from the best clinic in the country: http://www.mayoclinic.com/health/vaginitis/DS00255

I don’t think you have Vulvodynia, but you can read all the information and judge for yourself. You can print it out and take it to your doctor and ask them: http://www.mayoclinic.com/health/vulvodynia/DS00159/DSECTION=treatments%2Dand%2Ddrugs

My third and final guess is that there may be some hormonal imbalance going on with you. That can cause all kinds of problems. A physician would need to check your levels and prescribe any necessary medication.

You are not alone. I know it’s frustrating as heck and every day is a struggle, but you’re a fighter and you can get through this. If you aren’t getting anywhere with your doctor then go to someone else, but don’t let them send you away without a diagnosis, in pain, and emotionally shattered. Hold on. Okay? (hand squeeze)
