yes, my shoulder pain got me sent to the ER 7 days post op... luckily there was no leak or abscess which my doc said usually shows early signs around this time. However, d/t lapband removal, hernia repair and bypass- I too was under longer with prolonged period of 5+ hrs of CO2 being pumped into my abd...and they said I still had alot of air in my abd which puts pressure on your diaphragm sending sensory nerve pain to your shoulder! Walking and pain meds helped. Gas is finally fading at post op day 11, but incision site under left rib hurts. I had a drain there prior to hospital discharge too, so that "hole" is closing.
