Severe yeast infection? herpes? other things that causes sores/blisters? i'm now realizing i've had the symptoms of a yeast infection but i didn't get it treated because i wasn't thinking anything of it at the time. now i believe it's gotten a lot worse.

Hopefully : Hopefully you have a diagnosis and are under treatment. In this situation there is nothing you can do prevent the mores sores or blisters from appearing. However, if you know the signs of a yeast infection and think you have one, go ahead and treat with an over the counter yeast infection medication, and see your doctor if you have no improvement. Take care.
