It sounds like a partial or total obstruction to me. I have partial ones and rarely throw-up. That's why I am guessing yours was a total obstruction. If I were you I'd stay on soft foods for longer than a day or two. Things get swollen inside during these "episodes".
My surgeon told me I would have them from time to time and basically to live with them after he ordered a small bowel study. It's the test you drink barium on a empty stomach for. They x-ray your abdomen to look for kinks, blockages, narrowing etc, in your intestines. I didn't have anything like that but it took hours for the barium (water) to make it through to my j-pouch the last test I had. I'd had one a year before that took a lot less time. 2.5 hours compared to 30 minutes, that is why I think your irritated area might be swollen for a while.
I have a lot of adhesions but they don't operate unless they cause major problems. Each time they open you up they add more scaring so having a surgery in it's self could make the problems worse.
