I don't have any physical "sores" just more-sore spots. My vagina is extremely itchy, and Vagisil helps for the most part. I'm almost certain I got this irritation from the last person I had sexual contact with.

There is a piece of equipment manufactured by a Chinese company which will cure this in about 15 minutes Basically it uses ozonated water to wash it which kills all virus and bacteria within a very short time. I don't know where you are located so can not say if such equipment would be available where you are

My advice is to seek medical help,go to your doctor,get tested for any std/sti's and follow their advice for any treatments.
