@cgbi Sleep would have been a problem for me without medication. That was really the only time I did take any medications.
My doctor has a great track record, but his philosophy is quite different than typical. He does not believe in icing for the first six weeks. It does bring the swelling down a bit, but it also prevents the healing blood from getting to the site, delaying healing. He is also opposed to rigorous PT.
After my second TKR, I had more pain than after the first one but it suddenly lifted, almost overnight, and then I was able to walk all over the place! My TKR was on October 25, 2017. I was walking all over NYC on December 8th. I was really upset a week or so before that because we were going to NYC for my daughter's wedding reception and I thought I wouldn't be able to be on my feet much but I was amazingly fine.
My flex is still not what I would like. I saw my ortho last week and he said he can do a small outpatient procedure that will give me better flex so I think I will do that after the first of the year.
So, stay positive, and hopefully your recovery will be as good as mine was.
