It was painful, but when people say "It hurts" I wondered about the level of pain. Wind up getting in the chair and seeing that what I expected was not what I got. My concern wasn't the pain but how my body would react, I didn't want to move and F it up while he was doing it. However, it was not close to how I thought it would be and that helped me deal better, going in expecting something bad and getting it easier than I thought. My arm just relaxed and when you get it done, your body releases something that just numbs the pain after a while.
I literall just sat there leaning my head on my shoulder and watching and talking to the guy, it was a great experience. I'm glad to have gone through with it and getting to know what others have talked about!
