MSM may help with the chronic pain, too. I started taking it after reading a pamphlet from a natural grocery store which discussed studies done on MSM and osteoarthritis pain. In a nutshell, most people quit analgesics once they began taking 500mg. per day.

A daily dull ache was creeping into my left knee, which underwent ACL reconstruction last year. I saw quick relief once I started on MSM, in addition to glucosamine, and can feel it when I haven't had my dose.
