I've gone for obstruction pain--the type that comes in awful waves like labor. I average about 4-6 partial small bowel obstructions a year. I wait for 10 or so hours to see if it will resolve on its own, and if it doesn't, I go to the ER. I know once there I will be stuck in the hospital for 7 days with an NG tube and on steroids so I try to get through the pain with vicodin at home. Luckily, since my last surgery this summer, I've only had one and it only lasted 8 hours so I'm feeling hopeful they really removed the problem area this time.
