From what you're saying about not needing pain meds, I don't see why you aren't walking outside carrying something. I worry that you're depending on support rather than strengthening your leg muscles to provide that very support. This may be the result of having one leg done. As I had both, my recovery was even, not being able to depend on the "good" leg.
I just wonder if this is a confidence issue. Obviously, I don't know what (i'm talking about, hehehe) you're feeling, but I'm trying to put myself in your place (having been there.) After all, I'm just a week ahead of you. If your knee is stable and you don't feel pain, except for that one spot, which is normal. (At times I feel pain, on the inside which is the quad that they cut into for access, and outside, which is the IT Band) but I take that as normal and part of the healing process.
Anyway, I'm just rambling now, but I think from that all that you said you can do, I believe you can do the other things you want as long as you're willing to step outside of your comfort zone just a little bit, SAFELY, and believe in yourself.
