LJ55....We have the exact same surgery date, mine is the left also. I also have the tightness and also pain, especially if I overdo. Today for example after using ice and peddling for 8min. just to loosen up I'm out the door for a 30 min. drive to the library. Spent 3hr. there doing continuing ed. then back out to car. Visited restaurant then on to warehouse grocery. Very busy today I guess for Thanksgiving. Walked for 20min. or so then back to car and 30min. drive home. Iced as soon as I got home. Knee uncomfortable and hurts to walk. Icing again at 7pm. Oh, did I mention tylenol and advil all day? If I stay home and do minimal housework, cooking I'm ok but any extra sets my knee off. The thing that bothers me most is standing for an extended time, 10 plus min. causes pain everytime. My right knee is bone on bone and needs to be replaced too. I just can't right now, just cant......
So I'm right there with you, seeing improvement just at a snails pace, a disabled snail. Hope your stiffness resolves soon, hope your pain level is good this week too.
