Wow, I can't believe that when someone goes in complaining of severe pain and constipation, they don't even do any sort of abdominal scan to check for a blockage. Constipation is serious; you can damage your intestines going too long without going. I think I would have said, what the heck are pepcids for? I don't have heartburn. I can't poop, man! POOP! Do you know which end that comes out of? Why do you think I'm here? It's because OTC stuff hasn't worked. I need real medicine! I need professional help!
Back when my mother was working at a hsopital, they wrestled constipated people down and dug impactions out of them--after giving them several enemas. I don't understand why suddenly it's become less serious than it used to be.
I hope you can get to someone quickly who will get you cleared up. Have you tried just using some of the Fleets phospho soda or the golyghtly stuff that they give people who are prepping for a colonoscopy? You can get it at the drug store. That cleans almost everyone out. I'd tell you to ask a doctor first about using it, but heck, you don't have a competent one to ask! Maybe ask the pharmacist about using it to clear up your constipation. But some people who have flushed their colons out that way or with an herbal product have said they had a couple of good days afterwards before getting constipated again. Sometimes just a little temporary relief is good.
