I've only had one.
I have some start but I can tell now when the feeling comes up. That is with my permanent ileo. I will start feeling a pain on the other side of my stomach. Then I know I have to take action. It very subtle. But i know now.
The first one that sent me to the hospital was with a temporary ileo.
14 hours they dug around while i writhed in pain (excruciating I must say) worst pain I have ever felt in my entire life and i hope i never have that again. They had to do my second surgery to find it. This is a long story. So I'll cut it short. But it did put me in the hospital bed for 19 days.
Pay attention to the signs and take action if you have an end ileo . I chew well and I can still feel one coming on.
Just be self aware. Best defense.
Get up and move. Drink water. Don't eat.
