@Celle, okay, I get it. Thanks for the link and for the advice. I think I'll try the 8am-2pm-8pm-2am Tramadol/Acetaminophen routine suggested earlier and see how that goes today and tonight.
Today was my first post-op appointment, twelve days after the surgery. Surgeon seems happy with my progress. There was a stitch at each end of the incision that was removed today, and all the many steri-strips were replaced with only about half a dozen new ones. All other bandaging was removed. I'm cleared to shower with it uncovered now, yay. Got a souvenir print of the before and after xrays. He confirmed it's a Zimmer titanium knee.
He did no checking of range of motion yet -- said that's next time, in four more weeks. Laughing, he said he has a medieval torture device he'll use on me if I'm not up to snuff by then, haha. ('Tain't funny, McGee. Yikes.) Referred me to a local PT place near home for 12 sessions, twice a week, outpatient. I'm thinking I may give myself a week of rest and then start that week after next, and see how they approach helping me with my healing.
Asked about using the pool (I miss my water aerobics classes), and he said wait a few more weeks to be sure the incision is completely healed. Asked about driving, and he said any time I feel ready and am off the daytime pain meds. I'm not quite there yet.
Came home to an in-home PT session, second to last visit, and that guy seems really happy with my progress. Showed me an extension exercise of tightening my kneecap and flexing quad muscle that is interesting -- not painful, just interesting, to be able to do that. All the other exercises he had me do today were gentle and pain free. Actually I'm starting to feel more confidence in my new right knee than in my shaky/arthritic left knee now.
Asked the surgeon when does he think I should get the other knee done, and he said let's talk about that at my next visit, mid-April. He said some people have such a hard time with the first knee they want to put off the second one. Others do so well recovering from the first they want to move right along with getting the other one done too. At this moment, I'm there -- let's just get 'em both good so I can walk well and confidently again for the first time in years. And pain free, ultimately, of course. So don't hold me to this but I'm thinking maybe August for the left knee. Or September.
Now with all the walking into and from the surgeon's office today, then into and from the pharmacy on the way home, and then the exercises with the PT, it's time now for elevating, icing, and rest. (What was most painful about today was sitting in the car. Something about the angle of my knee and lack of support made that really hurt.)
