Thanks for everyone's replies.
The procedure was yesterday afternoon. So far no pain, just weakness in my legs but I haven't been moving around much yet. The injection was as you all said, like several bee stings and done before I knew it. There was some pain as the medicine went in but nothing I couldn't manage. I'm praying it works for me. Guess I'll know more in a couple of days or so. Thanks again to each of you who replied with all your information and well wishes. I really appreciate the help
