Yeah. I've had it done, post surgically (so there was scar tissue there to try and avoid) in my lower back. They insert a catheter directly into the affected area. What is injected is not a pain reliever, but will minimize the swelling; which in turn, minimizes the pain. Hubby will be having this done shortly for his shoulder.
It's painless except the needle stick. When mine was done a few years ago, I had to be taken to and from, too. But the numbness wears off in a few hours. I always was driven back to work. Didn't affect anything I had to do, really. From my perspective, it shouldn't interfere at all with your meeting the next day unless you have a bad (unplanned) reaction - either to the injection itself or to the numbing agent they'll use on your skin.
I don't believe they knock you clear out for those. At least they didn't used to. Good luck!
