Hi, You are having pruritus ani and pruritus on scrotal skin. There are may reasons of pruritus in both area. Irritation, allergy, fungus, any other skin disease or internal disease. Some time no cause is found, in that case it may be psychogenic in origin. Keen thorough examination and complete history is must. Routine and specialized blood test may be done. This should be done under supervision of dermatologist. He may give antihistaminics, steroid in tappering dose and antipsychotic drugs. Combined sterid and anti fungal cream may be applied. Sitz bath in dettol water for improving local hygiene is required. Soap should be avoided. Avoid tension and worries. If needed, internal disease should be treated. In anal area, piles and fissure in ano should be ruled out, for that surgeon should be contacted. I hope you got my answer...ok Regads. Dr. Ilyas Patel MD
