My dad has cancer (myeloma - 3.5 yrs since dx) and is in and out of hospital, usually on haematology ward - where generally most patients are fairly independent, in terms of getting to the loo etc.
But my dad had major surgery (metalwork inserted) in left arm AND left leg a week ago, and has an unstable spine - wears neck collar and has limited movement. He is only 62 and had always been very active and determined, so he does as much as he possibly can himself. But atm he is very dependant on staff, which he hates. (He can now get out of bed, but cannot and is not allowed to do so unassisted.)
He knows they are busy, but if he needs anything he needs help basically, and sometimes it is quite urgent. When he presses his bell it takes up to 30 mins for someone to respond, and sometimes they then go off and don't come back.
When my mum went in this morning he had basically been waiting for over an hour to go to the toilet! There had also been a query about his drugs at 8 am, so when she got in at 11.15 he hadn't had any pain relief at all that day 
(he's on quite a lot of morphine) or anti-sickness drugs, which he'd asked for.
My dad is wary of saying anything as he doesn't want to upset staff, but my mum is absolutely furious with the care he's getting.
Any suggestions?
