I had RT and HT (Zoladex). 37 sessions of RT, actual treatment fine. I had bowel problems for a while, meaning urgency, no problem whilst at home but I did have a few accidents whilst out, quite degrading but no lasting issues, this started maybe 4-6 months after RT.
I was on Zoladex for 3 years and have to admit to several expected side effects. HT finished June 2018 still carrying weight around stomach, still couple of night time hot flushes etc but looking back I'd do the same (tho only choice was HT/RT). I also had 2yrs of abiraterone, enzalutimide & steroids included in the 3 yrs as part of trial.
