Welcome, Dawn. I'm so sorry that you've had extreme pain and legitimate health problems and have been treated so poorly at the hospital.
Is there a different hospital you can go to where the nurses and doctors might be more compassionate?
I've had several small bowel obstructions and a ruptured small bowel, all caused by scar tissue from surgery, and would have died had I not gone to the hospital each time. I know you don't want to go, but if you're in pain and think you have an obstruction, you have to call your doctor and go.
If the obstruction is caused by scar tissue, then there's nothing that I know of diet-wise that you can do to keep it from happening. From my experience, I would have obstructed even on a liquid diet.
Please keep us posted on how you're doing.
Hugs, Cece
