In 1997 I hadmy L5S1 removed through surgery. Because of a retained segment I took Naproxen daily for pain. Another surgery was no an option. Since starting at Freedom, I am off Naproxen after 12 years. I am feeling my best concerning my back since my original injury in 1997. You need to do this for your overall health and stop taking harmful $@!#%. My time on NSAIDs did not cause liver damage. I am more fortunate than most.
