Even a reaction to the Local Anesthetic or any of the post-operative medication would have been systemic i.e. The reaction would not have localized itself to one arm. You also have a possible history of possibly having slept on that arm. Most likely you may have unknowingly sprained or pulled a muscle. Rest assured that it has nothing to do with your extraction Hope you feel better soon.
