"after only being on this medication for a short time for a l5 s1 back problem, it hasn&#039;t helped at all. i get more relief from 800mg of ibuprofen. have to wait 12 days to see a surgeon and god only knows how long before a surgery.  in constant pain and none of the medicines i have been given work. guess i&#039;m just one of those that can&#039;t be helped."
