Read about it and it sounded like a good idea for my 61 year old slightly-lumpy back. Thought that if it went well, might do front in the future.
Had a zillion shots of lidocaine and each wore off in a few moments. Procedure was HORRIBLE pain that lasted for an hour. Have been in pain since, now 6 weeks, diminishing little by little and my back looks a little better. Just a little.
I would never do this again. I am no baby and have been told always that I have a high pain tolerance, but this was a tooth-grinding, awful experience.
