I have completed 8/20 sessions. The procedure itself is not too bad and the staff are wonderful. However, I have hit a problem. For the first two days after treatment started I was unable to pee and was in such pain that I had to go to A&E who fitted a catheter which gave me much needed relief. The radiotherapy staff can continue with treatment which is a relief. Is this a known side effect or was it just an unlucky coincidence?
Hello Rawsoftba9a24
I wasn't sure so I checked my resource bank and it's one of the rarer side effects.
The radiotherapy can cause the prostate to swell and it can also lead to inflammation of your bladder and urethra and stop you emptying your bladder.
As an aside my prostate grew without any radiation and stopped me peeing (click on my avatar for my journey) and I ended up with a catheter for 10 months - so if you need any help in that department just drop me a message.
Best of luck with your final 12 fractions - keep us posted as to how you get on.
Best wishes- Brian.
