"i have been a chronic pain sufferer for over twenty years. i take some heavy duty pain medicines and still there are just not enough medicines some days.  it truly surprised me how well this medicine works. i can&#039;t take nsaids for more than a day or two without causing tummy troubles. i keep a tube with me now at all times. i highly recommend this to anyone with muscle or joint pain. i&#039;ve used lidoderm patches and tens unit, probably been on every possible combination of medicines. this medicine really helps me."
