I am 67 and undergoing radiation treatment for Gleason 6 prostate cancer. I am at the halfway mark. The first week or two went fine but now I have developed bladder and rectal issues. I am having night time bladder spasms that went from needed to urinate every 45 minutes to an hour to every 15-30 minutes. Sleep has become impossible and am now on day 3 with no sleep. I am currently taking Flomax and my Dr. suggested an OTC product called Azo but neither are of much use. I am trying to cut back on fluid intakes but the medications suggest taking with a full glass of water and I also have to have a full bladder for treatments. I have also developed bowel issues including bleeding hemorrhoids. This is requiring the use of laxatives which also affect my bladder. The radiologist and urologist have been of little help saying this is a common occurrence although they downplayed it during my consultations. In hindsight I wish I had gone with surgery. I am at wits end and wonder if anyone else has experience similar side effects and found a way to treat them. I need some sleep! Thank you!
