Thank you all for your support. Dad was fine,I phoned the home first, he wasn't dressed, but he was by the time I got there. He was quite cheerful, he didn't realise that I hadn't been for a while, he remembered my knees were bad, but not about the operation. We took a few old family photos to talk about, which he enjoyed, I also showed him one of my aunt - his sister in law, who is almost his age, but he couldn't come to terms with that, insisting it was his mother in law - my grandmother!
My knee has been good today, I've decided as I'm up and about a bit more I will take a second dose of paracetamol, at lunch times, and use ice more than I had been doing. I feel stupid for not realising that I can't do more activity without irritating the knee, but if I up the medication, my knee will cope with a bit more activity. All I've done today are a few stretches, a bit of 'walking' on the mini trampoline, and just normal walking whilst out and about visiting and afterwards at the shops.
I hope everyone is well, xxx
