I am sorry about your suffering dear.
Whenever I had obstructions with my ostomy, I always went in no matter what. The doctor said I always did the right thing by coming in. I think its better to be safe than sorry. I always like to plan for the worse, that way I am always prepared and ahead.
A few tips for the future for possible prevention: Drinking water before, during, and after every meal. And moving around after eating. Those tips help me always. A lot of people say those tips work for them as well. I hope this helps for the future.
Would definitely recommend going to the hospital. Hope everything is okay, keep us updated
