Hi.. Welcome to HEALTHCARE MAGIC. As per your complain it seems that itching in anus that is lasting since 12 moths can be due to causes like Poor hygiene maintenance, over wiping or cleaning, dryness in the anal area, pinworm infection,yeast infection,contact dermatitis or allergic reaction, hemorrhoids, anal fissures etc.. As it has not resolved with creams like Proctosedyl that is a steroid based cream and Canesten that is an antifungal ointment therefore you should consult a Proctologist and get evaluated and a proper diagnosis and investigations like microscopic examination of scrapings from the anal area, blood tests, anoscopy etc can help in diagnosis and treatment of underlying cause can relieve the symptoms.. As of now you should keep the area clean but avoid vigorous wiping.. Wash the area gently with water and a mild moisturiser based soap.. You should apply Zinc oxide based ointment or Petroleum jelly over the area.. Take anti allergics like levocetrizine or benadryl to relieve itching.. Wear loose fitting and cotton undergarments.. You can also apply steroid ointment to relieve itching but do not use for a long duration for more than ten days to two weeks.. You should avoid scratching the area to prevent infection.. Hope this information helps.. Thanks and regards.. Dr.Honey Nandwani Arora..
