The title of this thread is "beginning week five," but this is my eight week update. I can't believe the weeks have passed so quickly.

I remember well the nights I woke up crying, the exhaustion after PT, the nausea and the constipation. Things are so much better now.
Just a few weeks ago, I couldn't imagine where I would be today. I stopped PT last week with a ROM of 138 and 135 and an extension of 1 and 2. No more PT, so no more measurements, and that works for me. I think the numbers are less important than what you can do with your new knees. I'm at the point now at which I can do much of what I did before surgery--cooking, cleaning, taking the dogs out, shopping, doing the laundry, etc. I'm still a bit more tired than I used to be, but even that is getting better.
Nausea and constipation are totally gone so I'm back to eating normally--maybe a bit too normally if I want to lose some weight, and I do. No pain in the knees but aches in the legs persist. I don't have swelling after activity, but there is still a small swollen area on the right knee that I've had since surgery. I suspect there's still a lot of healing going on there.
Sleep is much better. For the past three or four nights I've awaken once or twice but easily went back to sleep. This has made so much difference for me. Before, I found myself exhausted by 7:00 pm; now I can go to sleep at an adult hour, a good thing because I have an evening wedding to go to in a few weeks.
What has really been great is the medication schedule. I'm on Tramadol and Tylenol. The past two nights, I took the medication at 6:00 pm and again at 11:00 pm, and the great news is that I didn't need to take the medication again until the morning and probably could have waited even longer.
I am seeing progress every day, and there haven't been many setbacks, so I count myself as one of the lucky ones.
This is my note of encouragement to all of you just beginning the recovery process and those who are soon scheduled for surgery. It's not an easy process but it DOES get better. For some it will take a little longer, and some will feel better more quickly, but it will happen for all of you.
