They named it tennis elbow. Most people who have it have never played tennis — plumbers, lifters, grapplers, pickleball players, anyone whose grip does real work. And it was never the sport. It's four millimeters of extensor tendon anchoring into the bone at your elbow, loaded by every grip and twist you've ever done, and never once fed. That's why the brace didn't fix it. The brace squeezes it. Ice quiets it. Glucosamine aimed at cartilage, which is a different tissue entirely. None of them hand a fibroblast raw material to lay new collagen fiber with. One ingredient does. 800mg, daily, ninety days — because tendon has the worst blood supply in your body and needs the deliveries to actually show up every single day.
Not enough history yet to show a trend.
