The rate of nerve recovery is anticipated to be 1mm per day, so in large nerves such as the sciatic nerve, recovery can continue slowly and take up to
a year for results. The rate
of nerve recovery
is also dependent on the length
of time the nerve was compressed before surgery was done.
There may be residual numbness/pain that is permanent, but given time, you should see improvement. As the severity has decreased since the operation, continued recovery could be anticipated.
