Shoulder replacement surgery

well i never had shoulder replacements surgery , but 3 days ago i just had a rotator cuff surgery on my shoulder for the second time in 3 years and both times its been very painful ,i have what they call a pain pump connected to my arm that shoots pain meds into the shoulder every so many hours and i'm also on percocet for pain and i cant even sleep for more then an hour or 2 because of the pain,so take it for what its worth,the only thing i can say is that maybe because they are replacing your entire shoulder they will have you on a stronger pain med then me,so good luck my friend and i hope all turns out well for you...
