I tried cortisone shots when I had issues with my hip and lower back...and years ago with my ankle. It hurts going in, but definitely feels good when the needle is pulled out!!! The negative part is that the relief does not last (for me a week to ten days was all I got). You can sometimes get relief with exercises that can be taught to you by a physical therapist. That also takes awhile to take effect, but I almost think that the relief lasts longer and it helps to strengthen which ever tendons are affected.
