Hello,
This is Dr. Klarida Papaqako answering your question.
Anal itching is usually idiopathic, probably
contact dermatitis.
Other dermatologic disorders may be
lichen planus, lichen sclerosus,
psoriasis, seborrhea, infection - fungal (Candida), herpes, condylomata acuminata, pinworms, scabies or anorectal disease - fissures, fistula in ano, proctitis, prolapsing hemorrhoids, skin tags,
sphincter dysfunction.
Treatment is decided according the cause which need a doctor examination of the area.
Meanwhile I would recommend:
-- avoid any foods which appear to aggravate condition (for example, caffeine, spicy foods, citrus fruits)
-- avoid perianal irritants (any creams or other care products that may be causing irritation, excessive cleansing with soaps, excessive rubbing with toilet paper or wash cloth)
minimize moisture in perianal area (wisp of absorbent cotton in anal cleft may help keep area dry)
--
hydrocortisone 1% ointment, once-twice/day appears to reduce symptoms of itchiness.
Hope this helps,
Regards.
