Rey Mysterio recently commented on an injury that he suffered in which he separated an acromioclavicular joint in his shoulder.

 “Thank you @thelabprc for putting me back together & always looking out for me! Highly recommend any athlete or non athlete with injuries to stop by and let them look out for you! #TheStaffIsNumero1 #Cryo #Sauna #PRP #MuchLove.”

In the video, he notes he separated the joint but hopes with therapy it will improve.
