Hi, I do know about being afraid of the IV stick. I too have no veins, but the OS was able to use a very very small needle, and I didn't have any trouble whats so ever. This took all the stress away! I also have to do something like this with an endoscopy on the 24th. I know it will be OK, they will take the very best care of you. The IV sedation for me was the best way to go, as I have the jitters over whats coming at me just like you do. Try to trust that this will be OK, and get rid of that bad old infection. I wish you all the best, ginnie
