It wasn't bad at all...I mean you do feel one jab actually mine was so quick then the rest of what he did you do not feel at all....I was already on my anxiety meds..you may want to ask if they can give you a little ativan or something...but I was back for my procedure so fast, in and out within the hour....do put ice pacs on your back though, they should tell you this, and I did notice my back felt sore for a few days...and dont' bend and lift stuff,,,,,anything I missed? I was tired, but then again I had to get up early for me and I am always a mess if I don't get my 8 hours! Good luck. You'll do fine! Let us know how yours' went ok? I have to go back Friday!
