My dad finished 4 weeks of radiotherapy last Thursday (he has locally advanced prostate cancer Gleason 4+5) and is having very little sleep at night. He is waking every hour, sometimes twice an hour to wee. He says is painful but not coping well with tiredness now. He has asked for some assistance with drugs but keyworker has told him to wait a few days - feels like a nightmare for him. Does anyone have any advice?
