The hospital has been my second home. If you are in alot of pain, not pooping and or vomiting, best to go to ER. It could be an obstruction or enough pain that you cant drink water and keep it down. Been there so many times. If you pass blood, especially if you are not a bleeder. Being dehydrated and cant get your meds down, that is problematic. Let us know what you are feeling or what you decide to do. Hang in there.
