they're kind of like jello shots but not as much fun. I got them in both knee joints. I won't take steroids because of my diabetes so I opted for the gel shots. it takes up to a couple of months for it to work completely throughout the joint so no instant relief. very little discomfort. the NP that gave them was good. he had done it before. barely felt the needle due to the freeze spray applied first. found out I don't need new knees. just arthritis with a few little bone spurs. also prescribed Mobic, a 24 hr anti-inflammatory. hope things get better soon. i'm way behind on yard work and honey-do's. lee
