Just found this thread. It just shows that being bipedal was always a bad idea …
just under 20yrs ago, I herniated L5/S1.
Severed the nerve to my left Gastrocnemious . Took at least 2 years to walk reasonably straight. Continuous pain, and lots of random unwanted leg flicks. Still look like an idiot if I try to run, but I can do 25Km walking days now.
However, bearing in mind that everyone’s damage and experience is different, I found sitting in a car seat driving, or maintaining symmetry on a bike was a ‘really good thing’. Twisting and shocks set me back weeks at a time, which is a bit troublesome as I’m relatively hypermobile.
Having lost the left calf, I spent about three years on a Wattbike training my pedaling to even out the power. It has been interesting ( as a biologist ) watching the different bits accommodating the change.
Totally opposite to what my surgeon said, I did not recover in 3 months. The leg flings went on for 15 years or so, until a White Van decided to hit whilst I was out on the bike. Hit my head, went into super spasm for about 4 hours, and came out the other side with no random leg flings. Yay. Result. Brain chemical reboot. Yay.
Anyway, advice I’d give is by all means listen to other peoples strategies and actions, but in the end, you have to find out what is best for you, and what works best. To echo comments above : move, move, move. Doesn’t matter how slow you walk around the block, or pedal, or how much power you have right now, it almost certainly will get better, if not exactly what is was like before. But as you use TR, you know what the pain is for and you know what your body is saying to you.

PP - Having spent an hour talking to a couple of neurosurgeons about my reboot, they said, 'yes, we see it a lot, and have no idea what is happening… ’ Everyone is slightly different, even though we share the same basic biochemistry.
