28 yo. Chronic left lower back pain. Stretching etc isn't enough. I don't like to take meds like aleve (naproxen) everyday....I'm only 28...should I? Long term?

Uncover causation. Prior to attempting to self treat a chronic issue, it is far better to see a physician and find out why you are experiencing such symptoms. Then, appropriate therapy will allow remission. But, if you need to explore this further on this site, suggest a Concierge appt.
