Hi Phleb, gald you have got an appointment to speak to someone - take pen and pad to make notes or maybe record the discussion?
By all means ask about sorts of treatments and therapies, if you don't ask you won't know.
As for making this Gentleman comfy etc you need to be lead by him, where he hirts and resolve that, what things are difficult for him and find solutions as you go along.
Don't let him neglect his mental attitude either, often a low dose anti depressant can be very helpful.
One tip from my late husband to slightly lighten the mood - 'Don't march the entire family (including those he hasn't seen for years) past his bed, day on day'.
In his words, he began to feel like an exhibit.
Not an easy time for any of you, but always someone here to chat to, and often someone with more knowledge than me too.
