@nannybb All I know is they put the medicine in my right side rib area. Instantly I was in pain. It happened so fast, and felt like medicine traveled down my back to my left side groin. I think maybe they hit a nerve, or hit scar tissue which in return caused them to hit a nerve. My son took me, and he had to help me to the car. The pain left reasonably quick, like an hour or so. I could then put weight on my left leg, but was I ever surprised to see bruises on the left thigh. I don't know for sure what happened, but I won't go back.
