My problem is actually not cartilage related, I have a part of my right rotator cuff that looks like frayed edges of a rope on the MRI. I tried to wean myself off the Glucosamine/chondroitin sulfate/msm because of the cost and conflicting reports of it's success. Although, I swear it works because I only have pain when I run out or it's really humid, or I have to do tricky school bus steering in the winter. It is not supposed to work for anything other than osteo-arthritis issues according to reports, if it even works at all. Maybe it's placebo effect with me, but I might be getting back on it if the pain persists despite what the reports say.
