Do yourself a favor and DONT GET THIS CORTISONE SHOT! Not only does it hurt like a S_B, but it's not good for you.
I had carpal tunnel surgery and developed a trigger finger afterwards and was told to have 3 cortisone shots between my fingers on each hand. No way will I ever do that again. I almost went into shock. It's so painful and the doctor, who is a complete idiot and has no compassion for life itself, injected this stuff so quickly between my fingers that I nearly fell off the table and passed out.
This drug will do more harm than good, so spare yourself the pain, pain PAIN, PAIN. You will be in more pain from the shot than it's worth. It will deteroriate your tissues in the end.
trust me on this.
