And then I went for my second opinion consult and was over the moon with confidence in the new doctor, and booked a surgery right away.
That was your best move (and everyone's best move), choosing a surgeon you knew you could trust. Sometimes it comes down to trusting your gut. (There's some fascinating research out there about how our "gut feelings" are part of our subconscious cognitive system, processing information in the background, so to speak.) That trust in a surgeon helps us by making us more serene during recovery.
It was a really difficult and depressing time
It's gets harder, as our recovery becomes better and the memory of those pains recedes, to recall why we were so very desperate as to allow someone to cut into us, remove our bone, put in metal and plastic, and hope for the best. That's a dark place to be.
So really, who cares if I'm a little wobbly when I walk.
About wobbly... I've been walking nearly every day since I could manage 500 ft. At first I too had balance issues when in motion, like walking down a sidewalk. If I looked to the side, maybe to admire some beautiful landscaping feature, I would wobble! Looking straight ahead, or down at the ground (which I did a lot early on), was no problem. It was looking to the side, or behind me over my shoulder because of some sound, where I would misstep. It was a little unnerving. That didn't go away as my walking distance increased. It did, however, become less and less with time.
I was just noticing this morning on my walk that I can look to the side without any problem at all. I thought about your post above, which I read last night, so a bit later I looked backward over my shoulder just to see what would happen. Wobble. But it was just a little wobble. Still, not like the old days when I could look backward while walking or running and not miss a step. I missed a step, or rather nearly did.
All along, I've been chalking up this interruption of smooth movement to balance and coordination. I figure my brain is still "learning" my new knees. Responses to nerve signals might be off now by the minutest of microseconds, but to our refined reflexes and nervous system, that's a discrepancy from the old knees that the brain has to reprogram. I figure this wobble, too, shall pass.
