I went to the doctors about two weeks ago and I had a yeast infection so my doctor gave me a 3 day treatment. A few days after the treatment it burned further up during sex so I decided to take another treatment, but a 7 day treatment. Once again all the symptoms were gone but it burned only during sex for the first few minutes then went away. Today I felt a slight itch down there but not I'm the same place as when I had my infection so could it just be irritated? Does it just need more time to heal?? Also I know it's not an STD because my partner and I have only been with each other.
