Be sure he is communicating with his doctors - I needed to go on more powerful (RX) painkillers, a prescription strength anti-diarrheal. This stuff was not offered to me until I complained the OTC stuff was insufficient. Be sure he is adequately hydrating - mix in Pedialyte or GatorAde into his water. I needed IV H2O and Potassium. The last half of this treatment was no fun at all. If you have specific questions or more info on what you mean by "brutal" you may be able to get more useful answers. There is an RX silver cream and an OTC Recticare that really help with radiation burn in the anal areas. Also, I wish I had heeded advice abut cotton underwear - made a huge difference. This is a great place to get information, thoughtful advice, and support .... welcome!
