"i had nerve damage of the saphenous nerve as a result of a total knee replacement surgery.  i had terrible nerve pain that was getting worse over two years post-op.  norco helped a little.  i tried high doses of gabapentin and that did not help. my pain specialist physician prescribed levorphanol and it helped immediately. i take 2mg twice a day and feel no pain.  i have my life back and am grateful for this medication."
