Thank you to everyone for the kind thoughts and helpful suggestions. Yesterday was a very 'dark day' for me but thankfully today I feel a bit better. I was on lots of meds in the hospital at different times, including paracetamol, codeine phosphate, Tramadol, Oramorph, Buccastem, Cyclizine, Ondansetron (Zofran), Piriton, omeprazole and Fragmin injections, ( as well as the general anasthetic and whatever antibotics I got) I think the opioids have been the main problem, and I read that morphine can result in severe hypotension especially after depleted blood volume or with certain anaesthetics, and although my other obs were always ok my blood pressure stayed very low. I'm now getting all these drugs out of my system and am just on Cocodamol, it doesn't give good pain relief but has a lot less codeine, and I feel less sick.

I am using ice packs as you suggested, frequently but not for so long, and it is working well so far - thank you.
@GimpyGal
The Cryo Cuff only went on after the initial big bandage came off, but at home I am using ice packs wrapped in a tea towel to take the edge off the extreme cold. I think I am very much like you with pain meds and liking warmth! Also, thanks for the advice about elevation, I was not doing it as well as I could have, but I've now put a pillow on top of my wedge cushion and with the recliner right back am able to get my toes up above my nose.
This is all such a learning curve!

I did have Ondansetron (Zofran) in hospital, but it was not successful enough for me to keep on with the codeine. At home I use Stugeron for travel sickness and think this is probably as good as anything if I feel queasy. I also fished out a bottle of smelling salts, old fashioned I know, but quite helpful if you feel sick

It's funny you call your TKR Ralph, my husband bought me a gorgeous soft toy rabbit for Easter and his name's Ralph. He will be a reminder of what I went through (and achieved)!
@Happydale
Encouragement from caring people like you makes all the difference, I do feel and appreciate the loving wishes from across the pond and send hugs back

Feeling tired now, time for a nap

Love, Tabbs xxxx
