I feel your pain there Joe . I have 3 buggered discs in the back and 1 in the neck . The misses who has to have every gadget under the sun got one of those . I tried it and could barely walk for a week afterwords. Sits in the junk shed now and thats where its staying . Im so glad it works for you though and as you probably know as well as anyone every injury is different . If it wasntnt for morphine I couldnt get out of bed . That stuff has been my life saver . I seriously doubt I would be still here if it wasnt for that stuff . Cheers the pope
