"chronic back pain for two years. i have a herniated disc touching a nerve and a ripped disc. though my pain isn&#039;t severe over time it builds up to what feels like an endless spiral of pain. a few of these later and the pain goes and i feel like a normal human being again. i take for a few months and then i&#039;m okay until i find that next uncomfortable twist. then back on them for a short while. they have given me my life back."
