Hi John... Good luck with your vertebroplasty!!! I've never had that procedure but others here have had kypho...so maybe they can help you more. Do you know what type of fracture you have and at what level (thoracic etc)? Most people get pain relief immediately, and some have to wait longer so I hope you are the first type.
Follow your drs instructions on the limitations afterwards, all spine procedures are delicate and need time to calm down.
Let us know how it goes.
