I just started taking it for lower back pain from arthritis,ruptured discs, spinal mis- alignment. I have tried physical therapy,chriropractor, accupuncture,massage therapy,ultrasound laser treatments, osteopathic manipulation. I am usually into more homeopathic, herbal rememdies but none of these things have worked. I'm worried about damage to my kindneys and liver being on such a high dose of NSAID.
