"i have been on butrans for about a week. dealing with pain in my lower back for 25 years. have received epidural shots in my l5 s1 area to no help. was referred to a pain clinic. was given a script for butran 5mcg/1 hour. for the first time in 25 years i&#039;ve had no pain. this has been a god send. no side effects no anything. i keep waiting for the pain to come back and it does not. i actually sleep now, can do more activities around the house then i could before, i&#039;m not cranky anymore because of being in pain. so far no break through pain. hope i don&#039;t get that. all i can say is yipee i&#039;m pain free."
