Hi John.
I am not you, you are not me, we have had different courses of treatment. I have, however, received about
80 Grey of radiation to the gut and groin for prostate cancer and am willing to tell you about
my experience a little.
The side effects from the radiation treatments began to get noticeable maybe a couple of months after they were finished. Since they kinda washed in over the side effects from the surgery, the urinary SE's were all just lumped together. I couldn't tell if I had to go or not and it sure burned when I peed. Leaked when I sneezed or coughed etc, peed frequently.
The cooked colon SE's stood out distinctly. Intestinal distress and cramping, and frequent loose, explosive bowel movements. I spent a lot of my mornings on the toilet. I did kegels then for entertainment......
Those side effects ramped up in intensity up to the "side effect nadir" a little over 3 years after the radiation treatments ended. I spent all of Oct, Nov and 1/2 of Dec 2016 pretty much centered on my SE's. My colon considered the mere sight of a clean toilet to be a challenge.
A follow-up colonoscopy found I had radiation colitis and moderate intestinal diverticulitis.
Now, it still burns when I pee and I am not always sure whether or not I have to pee or poop on an every-day basis. I still have the cramps and touchy colon, but the severity has backed off since the SE nadir.
I have a friend who tells me that the SE's continue to abate over the years. I am looking forward to that, though returning to PCa treatment is gonna suck IMHO.
If you put your details in your sig line like the rest of us it would help us to see where you are at.
