First off, many, many thanks for all the help & support over the last week or so. It has been a tremendous help. Apologies if I haven't replied to every email I'd had .
My dad was moved to Calgary earlier in the week for some tests and it looked at one point like they would operate on his heart which he probably wasn't really upto.
There was a slight complication because they nicked an artery in his leg while they were doing it so he had some internal bleeding for a while but it wasn't too major and they sorted it out.
He was moved back to Lethbridge and has been given different medication and will have to take things easy and make some changes in his lifestyle (I can teach him how to be less active).
The best news is he came home today - he had just got back when I rang which was a nice surprise!
I am so relieved that the blood wasn't an immediate issue as it gives me time to present some of the information to him to try and ensure he doesn't make any 'mistake' over it.
I'm really looking forward to seeing him again.
