Alison, I doubt you will need painkillers for the CPM itself. Though you may need them for after the MUA. I can assure you the MUA is nothing at all like the TKR. I wouldn't lie to you about that. And this is coming from someone who was absolutely scared stiff before my TKR, never having had an operation before. It makes you realise you can face more things than you could before.

Try to rest as much as you can and keep hydrated
I think it was just a 24 hour thing and I've just felt tired today and still a bit off food - but basically ok.
When my chiropractor showed me the x-ray, my pelvic bone was slanted. He worked that out for me and then my right knee started acting up because of my gait and "my family inheritance" Sir Arthritis. Aside from my knee, I still walk a little funny because I favored that toe.
I'm hoping that 2 new knees will straighten things out.
Seriously, I'm hoping
and praying
that you get everything all cleaned out and moving again. I know it can't be easy. I've been complaining about the stiffness and the band around my knee. It's NOTHING compared to what you are going through. I'm looking forward to hearing a good report form you in the near future. 

some off my best conversations are with my cats
they listen unconditional,
but, it's morning here. Wishing you well today & hope it's over
