i had cellulitis in my left leg and i became septic. it has been over three months and from my lower back to the bottom of my feet are in severe pain and keeps getting worse like there on fire with knife like pains and they are getting weaker by the day it seems. i have been back to work for 4 weeks and i can hardly walk it is so bad. i am on nuerontin 1200 mg a day and it seems to help some but the pain and weakness are almost unbearable. i have been checked for blood clots many times and told its just nerves but its just so bad. what else could it be?
