Quit eating acidic things and spicy things. It helps a tonne to curb the infamation and itching.
Also wash area gently with a very mild cleanser. dab with hypoalergenic moisterizer (no perfume etc). Finish off with a cotton ball. This absorbs any slight leakage which contributes to the iching. I have had fissures and 'roids, this strategy works by far the best. I have used all the creams and ointments. Tell me how it goes.
