Summary
Regional anesthesia decreases postoperative pain scores and opioid consumption, and may
prevent chronic pain after surgery in patients undergoing surgery. However, some patients
experience an increase of pain into the severe range when the nerve block wears off, also
known as rebound pain. The investigators are studying if a nerve block (numbing injection) in
the arm causes hyperalgesia (increased pain) when the nerve block is wearing off.
