Thanks for everyones kind words.
Thankfully my dad is out of hospital. We have all had a bit of a reality check as there was something wrong. I just thank the heavens that it was picked up early enough.
He has had (another) shunt put into a collapsed artery in his heart and has been told to take it easy for the next two weeks.
I just hope that he will now take it easy and look after himself better.
But I’m so glad he is ok.
