I think we all feel like we “need to work at recovery” by doing PT after surgery. My OS told me I didn’t need PT to heal but like you, I thought I knew better and would heal even better with PT so I went to a few sessions. However, after a couple visits, I stopped going as it didn’t help me at all and nearly everyone on this forum said it wasn’t needed. I also noticed that most of those on the forum complaining about pain were the ones who went to therapy. I got my range of motion back just fine with no PT and you will, too. As others have said, ice is a huge help. Ice all day if needed as it really helps with any pain you might have. Your walks to the bathroom and kitchen will be enough exercise and as you feel better, increase your walking distance gradually. You will do just fine but you will need to find a bit of patience - well maybe a LOT of patience during the early days of your recovery. You don’t want to try and rush things as it will only set you back on the recovery. Read a good book, call some old friends - whatever you need for quiet activity so your body can heal. Wishing you well.
