Depends: Question re: peripheral arm weakness ; pain fr. Nerve damage is ambiguous whether disorders preceded or followed upon surgery. If existed prior then release of impingement should take no more than six months to reflect significant yet possibly incomplete healing. If disorders worsened post surgery then concern arises for medical misadventure ; iatrogenic injury that will likely remain permanent.

Months: Nerves in general "heal" at a rate of 1 inch per month, so if the muscles are 24 inches from the spine, it could take 24 months for the muscle to reestablish connection to the brain and start working somewhat normally.

Long term: Nerves can be damaged very quickly and can take years to repair themselves, unfortunately, sometimes no recovery takes place from my experience , if recovery occurs there is some evidence of improvement in first 2-3 months after injury.
