I have itchy vagina and realized theres like bad creamy discharge that is excessive. how can i get rid of it and can i dont go look for doctor?

Try antifungal cream: Most acute itchy, creamy vaginal discharges are caused by a yeast or fungus called Monilia or Candida. Try to get an antifungal cream like Monistat which you can apply once a twice a day for 3 to 5 days + simple feminine hygiene" steps like frequent washing with plain soap, keeping yourself dry, using a hairdryer, wearing loose cotton panties or none at all for a few days...otherwise consult Gyn
