I've started to walk unaided in small steps every now and then. For "partial" weight bearing (aka walking at home) instead of crutches, I use the walker, but I don't hold the walker. Instead I only keep my thumbs or index fingers on the walker for balance (you put almost zero weight on a walker with just your thumbs) and take steps. Sometimes I walk without a walker or crutches around, but it's in a very controlled environment with someone around and it's just a few steps. There's no real pain, but muscles get tired if I overdo it.
What I've learned so far:
-Precice 2 is sturdy
-You have to push yourself. I was very apprehensive for a lot of time and my left leg was (still is) lagging behind. Little improvement in taking full weight for walking in the left leg in the past few weeks while the right leg is soaring ahead. Taking DoingItForMe's bold decision to walk on his own during his journey as inspiration, I've been doing the thumb-on-walker method for 99% weight bearing and my left leg has improved tremendously in the past 4 days. 4 goddamn days, I kid you not. I'm going to say though that this is just my experience. I am not fully walking unaided without my doctor's permission, and I definitely don't recommend anyone else to either.
-You will have a hip sway to maintain balance. I suppose that goes with time.
I'm hoping that I'm allowed to walk unaided more soon. We'll see after my next x-rays. The worst part about my LL has been the time it's taken. The lifestyle change is so bizarre and I think my mind dissociates from it somewhat. For someone who's very extroverted and doesn't like video games, this would be hell lol. On the bright side, improvement is certain and constant.
Edit: to be more precise, when I tried walking unaided a week or so ago, my left leg's step would be fine (since the strong right leg is the supporting pillar) but the right leg's step would be smaller and hit with a jerk, since the weaker left leg wasn't providing proper support. With the right leg standing, I could take the left step in sort of slow motion, taking a lot of weight and landing a consistent, soft step- but with the left leg standing, the right step would be quick. Now, both steps can be done in slow motion meaning both legs are providing enough support at the time. This improvement has occurred over 3-4 days of pushing my left leg's limits. I'm not pushing it any further, because there is no further (the next step would be to simply walk unaided non stop) and I can't afford to break the nail at this stage.
