Hi Dr. Im A 33 Male Athlete Who Does Boxing

hi dr. im a 33 male athlete who does boxing and weight lifting, i was hitting the heavy bag 2 days ago during a boxing session and suddenly i felt my shoulder popped out forward with an intense pain and paralyze then felt it back in place within 5 to 10 seconds, and everything went back to normal with no pain whatsoever , i didnt go to a doctor as i completely feel normal , but talking a friend about it today he mentioned that its a serious injury and i shouldnt train or use my arm for 2 weeks is that true? and does it sound like a dislocation or just a twist since i have no pain from it?
