Vaginal itching: The most common reason for a discharge with itching is a yeast infection. If this discharge dribbles down it can also cause rectal itching. Your doctor can check the ph of your vagina, and do a KOH wet mount to look under the microscope to diagnose yeast. Yeast can be easily treated locally with monistat,terazol (terconazole) or nystatin cream. See your gynecologist.

It could be: It could be causing the itching by an infected discharge running over the vulva and anus. Have your MD re examine for the same, and if reluctant get a 2nd opinion from a GYN MD.
