Today I had a MUA procedure where they gave me 2 nerve blocks

Today I had a MUA procedure where they gave me 2 nerve blocks, localized pain injections, and anesthesia and manipulated it to break up the scar tissue that formed in hopes of avoiding having to go in fully for another invasive surgery.
The anesthesiologist said he experienced a new first today. After they had given me a light sedative to administer the nerve blocks, they wheeled me back into the operating room. That’s about all I remember until I woke up in recovery. He stopped back in afterwards and told me that as they started to give me the anesthesia I tried to get the whole room to sing Wycleff Jean’s Gone til November, and they gave into my request and sang with me as I fell asleep.
