This is really horrible stuff, Swifty. I'm feeling for you.
I've had a few incidents in my many hospital stays/appointments, which I should've reported, but didn't have the energy to. Being seriously ill on top of life's other trials really makes you pick your battles.
My poorly dad received absolutely dispicable treatment by one member of staff in one "rehabilitation unit" earlier this year. My response was to demand a bed elsewhere from head nurse (sorry, not good with medical titles) or else I would have to move into my dad's room with him, as there was no way I was leaving him there alone with that orderly working there.
When an ambulance couldn't be found to take my dad to the other ward in the other hospital in the next county, I called on my brother's help and we both got him the hell out there and drove him ourselves to the other hospital.
My brother made a huge noise about the complaint he was going to put in, but dad was dying and I just knew we wouldn't have the energy to do it, and we never did. I hope the "private word" I had with the head nurse (who seemed aware of this member of staff being a problem, and wanted me to put in a complaint) was good enough and that they found another way to get rid of that man.
I cried all day that day.
