The Use of Methylsulfonylmethane (MSM) in the Treatment of Low Back Pain.

FWH20140075H

The investigators are studying whether MSM plus standard of care naproxen improves symptoms of lower back pain compared to standard of care naproxen plus placebo. Subjects will be randomized into 1 of 2 groups. Group 1 will take by mouth 6000 milligrams (mgs) of MSM plus standard of care naproxen. Group 2 will take by mouth placebo capsules plus standard of care naproxen. Subjects will be instructed to take their study pills for 12 weeks and record on a study diary. They will then be followed up for one final visit 4 weeks later. RMDQ, PIQ-6, pain level, comprehensive metabolic panel (CMP), complete blood count (CBC) will be assessed at 4 week intervals for 12 weeks. Subjects' participation will last 16 weeks.
