I have gone in for a few of these and want to let everyone know what they did at the last one that was so darn helpful...so I am on my side with my arm bent over my head as per normal, then the assistant started tapping on my elbow with her fingers, not painful, but hard enough that it distracted me from the doctor giving the lidocaine injection, it worked so well I literally said to the assistant "What kind of witchcraft is this?" and laughed as she started to laugh as well. This is something that the doctors figured out at this specific hospital and they do it with everyone.
