After three years of living hell i finally had L3-4 & L4-5 prodiscs installed. With so much info being so easy to come by it can make decision making pretty f'ing scary when it comes to making a choice about your future ability to function. I had 3 previous surgeries each of which made things far far worse and each was followed by doctors telling me this was to be my life and i must stop taking so many pain meds. i was quite literally days from taking my own life. The prodiscs saved my life.
