question: I had a left knee replacement eight yrs. ago. Four yrs. ago I had a ruptured L-5 disc which caused bad Neuropathy in my legs and feet. I had a L-4 & 5 fusion surgery in 2010. In the last few weeks I had severe pain in that left knee for at least 12 hours and then it went away. Could that be the neuropathy pain? My email is YYYY@YYYY . Thank you, Judy Pata
