If you're passing stool, gas and not vomiting, then I can't believe it's an obstruction. People here who've described having an obstruction also talk about the terrible spasms they get when they're blocked.
Perhaps you have a stricture that is making it hard to pass food through causing temporary blockages. Why don't you go to your GI and schedule a scope and/or CT?
