Excessive white discharge along with itching and pain in the groin or vaginal area is commonly due to a fungal infection (yeast infection), though it can also be caused by bacterial infection or poor hygiene. Typical signs include thick white discharge, itching, redness, and discomfort. To manage this, keep the area clean and dry, wear loose cotton undergarments, and avoid using scented soaps or products. Antifungal creams or vaginal tablets are often effective, but since you also have pain, it is best to consult a doctor for proper diagnosis and the right treatment, which may include antifungal or other medicines depending on the cause. Avoid self-medication with steroid creams, as they can worsen the condition.
