Like I said earlier, I had a spinal block and they bend u over the side of the bed or operating table, give u a small shot, like a pinch, and then ur numb and get the big shot, I felt it going in my spine,but it wasnt uncomfortable or painful at all and within thirty seconds I ws numb, completely numb, its deffinetly not bad! I think its all in ur head if u think it hurts, too me, stubbing my toe hurts more! Lol...If u dont get one, itll b alot worse for ya!
