I been having an itching sensation in my vaginal area, i'm seen a lot of discharge and i mostly think is a yeast infection. i don't know what to do?

If indeed a yeast: Infection, you will need to see your physician for a script (anti fungal tablets) to treat it. In the meantime, you can use gyne lotrimin (clotrimazole) cream , vagisil and the like topically for some comfort.You can buy it over the counter.

Itching, discharge: Use an over the counter yeast medicine such as myconazole, clorotrimazole, etc. If you are not cured in a week, see your doctor for prescription treatment.
