It was not my shoulder blade, or calf for sure… I slept through both of those.
It was the inside of my bicep as it wrapped onto the backside of the bicep. I congratulated the artist and told them that they were the first to bring a single tear to my eye during a session.
About a year before that I had a 5 hour session with no breaks, that artist said he was surprised I never wanted a break. I told him I always let the artist dictate the breaks.
