I'm sorry to hear about the sleep problems still and the Reflux, but I am glad your range is still improving. I know I had a lot of weird aches/pains after my first TKR in 2019. I suspected it had to do with how weird I had been walking before the surgery but never had any confirmation. I still had loads of scar tissue from prior surgeries that my TR surgeon simply left alone (except in one area), so he said I'd still deal with some of the limitations related to that. It's simply amazing how many mysteries surround a TKR recovery. I find it shocking how no 2 people have the same recovery---whether it be complications, improvements, weird aches/pains, sleeping quality, etc.
I hope you keep seeing the improvements though. Hang in there!!!
I also meant to tell you that I saw your comment on MY post-op thread, and thanks for sharing about the cane. It reminds me that there are MANY of us not walking perfectly and back to normal at this point, and I'm not alone. I think that's the reminder I keep seeking everyday---that I'm not alone at this point in recovery, and SO MANY are struggling with certain things. I don't wish it on anyone though.
