I use terconazole cream 7days for 4days allready and my vagina still feel the same is that normal?

Talk to your doctor: First, make sure you have a yeast infection because terconazole will only work on yeast and not on bacteria. If it is yeast and the terconazole isn't working then you might need a different medication, probably an oral one. It is important to use hypoallergenic products, for soap, detergent, etc to avoid irritating the area. Low carb/low sugar diet is critical for curing yeast infections.
