I do understand about being nervous for the block. Sometimes you are allowed some IV sedation. I would ask for it before your date of proceedure. Most doctors are willing to help as much as possible. Also ask for plenty of local anesthetic. I have done some proceedures too that scared me, and I asked for more before it even started. I tend to be anxious regarding most needles. Even blood draws. I am a chicken at heart. It will be OK. Just talk to your doctor and ask for reassurances. They see alot of nervous folks. I wish you all the best. I will keep you in my thoughts and prayers. ginnie
