question: Hi I am 72 year old male and have colon cancer, there is also 2 in my sygmoid and one on my bowel.  I just had an absess drained from the same area of the sygmoid.  Since then I have had two treatments of Chemo and am having a terrible problem with severe burning in and around the annal area.  I must use the toilet often.  I have tried vaseline which helps to some degree and ora-gel  to numb the area.  Can you suggest any other treatments.
