I've had a rectal itch for a month and tried several creams and powders, including desonide. What other cream can I try to stop the itch?

RECTAL ITCH. A VERY COMMON COMPLAINT. CUT DOWN ON SPICY FOODS. DO YOU HAVE HEMORRHIOIDS? DIARRHEA? FUNGOUS OR YEAST INFECTIONS? PINWORMS, OR PARASITE INFECTION? WARTS IN YOUR ANAL REGION? DIABETES? NEW TOILET PAPER? IF NO BETTER SOON, SEE A DERMATOLOGIST BEST LUCK.
