I am feeling anal itching from few days......what should i do?

Anal itching : See your doctor to rule out pinworms, especially if you work with toddlers. There can be other causes as well.

Agree with Novick...: ...But if you don't work with children, you might have hemorrhoids, which can be very itchy; you might be using something irritating to wipe with; you might have eczema, impetigo (a skin infection), or many other things. You might want to try wiping with a clean wet cloth for a few days, then go see your doctor if it doesn't go away.
