My husband too had terrible pain after his LAR surgery to reverse his colostomy. It also took 24 hours longer for his gut to wake up than normal because his surgery was over 6 hours long, the poor guy threw up every bit of the liquid diet he had eaten that day. His pain was located mainly in his right shoulder, and the surgeon guessed it was either gas pain from trapped gas leftover from LAR or muscle discomfort from being in one position so long. So he would get his morphine, we'd wait for it to take effect, then try walking. We'd get only a couple of laps before the pain started getting too bad and he'd lay back down and nap. Repeat three times a day. I'm still not sure what the cause was, but after a couple of days the pain was lessening and it was gone by the time he was discharged; we were there a full week.
The nurses applauded me for making sure he got up to walk, but I know it was agony for him. To be honest I'm not sure if he would have gotten up and walked on his own if I wasn't there to coax him along. I wish you luck, and I hope the pain goes away soon!
