Hello. Chronic white discharge (leukorrhea) is very common and highly treatable. Because it has lasted for a few years, we need to identify the exact cause before treating it. If it is caused by a yeast infection, antifungal medications like oral fluconazole or clotrimazole creams are highly effective. For bacterial infections, antibiotics like metronidazole are typically prescribed. Please do not worry, as this is not a dangerous condition. I highly recommend visiting a gynecologist for a simple, painless swab test. This will ensure you receive the exact medication you need to resolve this permanently. Meanwhile, wear breathable cotton underwear and keep the area dry.
