Any Suggestion?

You have not indicated the area from where discharge is coming. It can be from nose or vagina. I assume you are asking about vaginal discharge. If the smell of the discharge is like rotten egg then problem is trichomonial infection. Trichomonas is the protozoan and usually transmitted through sex. It requires imidazole derivative for the treatment. If the discharge has fishy smell then it can be bacterial vaginosis. I recommend to visit a doctor for proper diagnosis and treatment.
