TweetI had it injected into my right knee (the one without all the ligament damage) to help my already very thin meniscus, which got shaved off in a prior arthroscopic proedure. It is a very weird injection. Think about someone sticking an inch long needle right into your damn knee joint. Not too bad as far as pain, but it is freaking weird ass hell. It seemed to help fairly well, i can squat heavy again without pain. Im going to schedule another 5 week session in the summer, i can feel the right knee getting sore from all the heavy squatting i have been doing early spring, late winter. My insurance sucks, so it cost me arounf $500 total, but it was worth it.
