I do so miss not being able to drive
I fully understand. We live in the sticks, and have to drive at least 15 minutes, and often longer, to get to any kind of shopping, other than a gas station with overpriced junk. I haven't been able to drive for so long, and am looking forward also to driving again. I hate having to be driven everywhere, I want my independence back! You'll soon be driving again, and will cherish the independence, and the return to a more normal lifestyle, even more after having been curtailed for some time.
I'm glad to see you realized PT was causing you more problems, and not helping, and that you had the courage to end the sessions. For many people, formal PT doesn't help, and sometimes hurts, but it's hard to get past the narrative that we must have it after knee surgery. Some people go to PT and enjoy it, and that's great, but for those of us who aren't helped by it, and some who are actually set back in recovery after each session, saying no is hard to do, but well worth it.
I had the home health/ PT in yesterday, all I allowed her to do was remove my dressings and check my surgical sites. She wanted to measure my ROM, and have me do some exercises; guess who won that "battle"......

It wasn't really a battle so much as she asked me to do some formal exercises, I declined, she also came at me with her goniometer, I told her to put it back...lol. She was slightly surprised, but nicely complied.
Understanding our limitations, but seeing where we can push ourselves without causing additional pain is a good thing, and one that's a delicate balance. You're doing great!
