I have white discharge problem for many years and am facing this everyday.
What shall I do for this?

You should setup an appoint with your doctor and get it checked out. Does it have a smell or texture?

How old are you? Why do you consider it a problem?

Women naturally have a discharge that can be white and is quite normal. It is what cleans and lubricates the vagina. Unless there is a strong odor or a strange texture then you probably do not have a health concern.

If you have itching or burning sensations in your pubic area and/or the discharge has a strong odor and/or different texture, then you should consult your doctor.

If you are concerned or worried, then you should talk to your doctor.
