This Is A Very Funny Question - I Have Been

This is a very funny question - I have been suffering with severe itching on my bottom area, from the back (Anus) to the front. I had a colonoscopy on Nov. 21 and I asked that doctor about it and she prescribed o Calmoseptine ointment and said to come in to see her, if that doesn't work. Somedays are better but today was not good day as the itching was severe again. I have an appt but not until Jan. 15th. What could this be?
