Hi,
I haven't used metro gel. I had discharge that did the same. I got rid of the itch naturally.
Hi there and welcome. sounds like you have a yeast infection. I don't think you are saying that the gel is causing the yeast infection but that this is what you are trying to use to treat it?
In all honesty, I'd make an appointment with your doctor. They make a pill that you take that really does a fantastic job of clearing up yeast infections. I would also add probiotic yogurt into your diet.
good luck dear
Id stop using it if I were you. Do you have bv?
