How long to recover?
The time it takes to recover depends on how much damage was done to the nerves. The greatest recovery will take place in the first year (according to my son’s nuerologist) but can continue to recover for quite some time.
Be careful not to overdo, but you also dont want to give up the part of life you enjoy. Starting some strength training might be very beneficial. Did you have any physical rehab? That might be something to talk to your physician even now a year later.
