opioid-induced constipation
"I hear a lot of horror stories regarding Movantic, but have not had any side effects; except for flatulence (gas), before going to the bathroom.  I had a bowel impaction many years ago, from a L4-5 fusion; and was never told that the Vicodin could back my bowels up.  Long and short, I had a bowel impaction, so badly; I go not go either way; and have to go to the ER, to have it removed.  It was the worse pain that I EVER experienced in my life.  I had an industrial accident around 6 years ago, and have had several surgeries.  I live in chronic pain, and take pain medicine daily.  I know how an impaction feels; and was heading for another ER visit.  Movantic 25 mg was my answer; I wish it was available 15 years ago!  A bowel impaction is a serious issue to deal with.  When you’re constipated, you sit a lot on the toilet; and do a lot of pushing, which in turn, causes hemorrhoids.  One thing that I have learned follows: I don’t sit on the toilet, until I feel the urge to expel my bowels.  Sitting on the toilet causes a lot of pressure on the anus, and that in itself will cause hemorrhoids eventually.  Let gravity do its job; as it was intended to do!
Good Luck!"
