I used to get cortisone shots every few months in my shoulder and hip and then, I was to start getting them in my knee. After the one shot, I never returned for another, it was that bad of an experience for me. I didn't mind the slight uncomfortableness of the ones in the shoulder/hip, but, that one in the knee, given by a different doctor, nearly made me want to put the doc in choke hold. Anyway, it didn't relieve the pain, so, it wasn't like I would have been returning for any benefits. That's my excuse and I"m sticking with it.
