Thanks for your reply.
There is not enough warning about the side effects of SRT, If the increase in PSA is moderate sometimes it may be better to go onto HT (it has its side effects) or surveillance---in hindsight I would have delayed having SRT.
I'm interested that you were considered for hyperbaric oxygen treatment; I've read about it and assumed that it is too expensive and lengthy to be available on the NHS.
Returning to HT treatment, I have a friend who had radiotherapy (private clinic) for P Cancer, that was about 5 years ago, he has been on HT ever since as part of the treatment. The side effects seem to be putting on weight, and loss of energy.
I'd be interested in how you get on with the trial.
