Thanks, all, for the replies - especially you, Shellyac....you made me think a lot. I'm actually quite terrified of needles. Do the fills hurt? I hadn't really thought about that aspect yet. However, I recently had a herniated disc in my back (weight related, of course!), and had to get three shots in my spine. I made it through those OK (OK....so I passed out....but I made it!). Do the fills put you "out of commission" or can you go right back to work?
Thanks again, everyone!
