Hi Brian,
I think having a one to one with your GP is a good idea and I hope something will follow that may ameliorate your condition. I would assume that you have already had dietary advice and perhaps physiotherapy? Another thing may help or at least be pleasurable is massage.
Unfortunately, I am well overweight and have reduced my intake of food and resumed a bit of sporting activity in an effort to reduce weight, even cutting back on chocolate and ice cream which are most likely responsible.
I still have a packet of Bicalutamide which I was asked to take after my HIFU treatment as a precursor to starting Zoladex but I am loathe to start it for reasons you will understand. However, if my PSA continues to climb I will seek other treatment (maybe more RT) and only if this does not work start the Bicalutamide. I think you might be right in as much as when the effects of medication cause more problems than they help with, it is reasonable to question whether it makes sense to take HT for your remaining time. However, it might be worth asking your GP or oncologist if there is an alternative you could try.
