Yes.....excellent advice.....and check your paperwork regularly for spots/flecks of blood. These can be very small, so look carefully. They can indicate polyps or piles but more importantly ( as in my case ) bowel cancer. It was only after seeing a few flecks of blood for the second or third...

Within 2 weeks, no more pain and none since.
