"i broke my neck at cervical levels c-5,6,&amp;7, in 1994;. i had tried everything (rx&#039;s)from codiene to fentynal patch to everything else associated with chronic pain and nerve damge. morrphine made me sick ever so often , but when i started on a methadone pain rx program, i was relieved from many of the severe, chronic and constant pain syptoms. it has been an excellent pain relief prescription for my condition now since 1995. i hope that anyone who has severe, chronic and constant pain symptoms try it."
