Hello,
It can be due to pruritis ani or the recurrence of hemorrhoids. So get an examination done by a surgeon to confirm the diagnosis.Till that time,try an over-the-counter (OTC) cream or ointment containing hydrocortisone (Cortaid, Preparation H),but it is to be applied sparingly to the affected area. A protective ointment that contains zinc oxide (Desitin, Balmex) also may help. If your symptoms are worse at night, take an antihistamine like benadryl to reduce itching until topical treatments take effect.
I hope it helps. Take care and regards.
Thank you for the advice. I will try this!
