Hi Retha, I'm 4 weeks PO PKR, and I definitely felt that 'starting again' in the morning feeling for the first 2 weeks and then suddenly, one morning I woke up and I could walk without pain and soreness. It's not permanently pain-free but in pockets. I know we are all different and heal/recover at different rates, one of the things I found helpful is to have the Paracetamol next to the bed, so when I wake up at 6am ish, I take my first 2 then, so by the time I actually get out of bed they have kicked in.
I drove my car after 3 weeks, but I had my right knee done, had it been my left there's no way I would have been able to drive. I'm not using walking aids any longer, although if I'm out in public and going to be walking with other people around, I take a stick just to give people the heads up that they should give me a bit of room.
I'm on Paracetamol and Ibuprofen during the day and Codeine, when I need it, at night. I'm one of the lucky ones, in that sleep hasn't been a particular problem for me, although I have had some 'restless' nights, but I just go with the flow and take the Codeine the next night to make sure I get a full night's sleep.
My routine is getting pretty tedious, I have to say, when I'm not doing my exercises I always have my leg elevated. Since I started cycling on my turbo trainer twice a day I 'feel' as though the straightening of my leg has become restricted. As of 2 weeks ago I had 110 bend, and I'm off to see the physio tomorrow, so we'll see if that has improved. When I first began the cycling it hurt a lot, but then after 2 mins my knee would free up and by the end of the 5 mins it felt a lot easier and I was able to do my other exercises with ease. The next day it was sore, but after 5/6 days it definitely felt better.
My head is telling me to do more exercise but I know that if I do I will suffer the following day, so it's a delicate balance between exercising and rest. I do hope you begin to feel better soon, are you icing and elevating? My sister in law is a Podiatrist and tells me that the happy number is 6 weeks, that's when the magic happens, an in any case, everything is relative. Good luck!
