cankle!!I'm walking around the house and outside everyday as well as stairs due to an upstairs toilet but don't know if this is enough or too much
I don't have a toilet on the ground floor either. You are probably doing loads just having to use stairs so much - so go easy on yourself. Be really organised to limit the number of times you use the stairs.
I remember having a set back about ( ? 10 weeks) with more pain and swelling again. At first I couldn't work out what had happened until I looked at my fitbit data and realised I had tripled my number of flights of stairs to 18! In the first few weeks I had had no problem asking my family to fetch things for me from upstairs but felt guilty by that stage and was going upstairs myself if I forgot my reading glasses etc.
Stairs are really tough on new knees.
Lack of sleep is absolutely normal too.
I am only now ( 16 weeks) starting to sleep better. Although admittedly I have been a poor sleeper for several years.
I asked my GP for some zopiclone ( just emailed and said I had had a partial knee replacement and couldn't sleep due to pain. No problem getting a month's supply on that basis. I use it sparingly and also use herbal valerian and a sedative antihistamine ( called Nytol in the UK) that you can buy at the chemist. I also have some melatonin I bought on a trip to the US.
I find varying what I use prevents tolerance. Also I still use iced water for pain relief and rest the jacket of my cryocuff on my knee at night. It is very soothing and helps me to go off to sleep.
