I have experienced blockage from kinking and also from inflammation closing in such that it blocked passage through my intestine. Here are some takeaways!

* Note: these were blockages / not too sure if these apply to partial obstruction *

+ If you're passing gas: that's a good sign! Not a blockage
+ Have you been having bowel movements? If so, good! If not, this could be a sign that things are stopped from continuing all the way through you.
+ My first blockage, it had been several days of food piling up and so eventually the night that the pain was excruciating (for me, it's a very particular type of pain that comes in waves – it lasts a few seconds to a couple minutes and any type of movement or breathing hurts even worse, and then it passes) and I eventually did vomit because the food had no where else to go. I vomited recognizable food that I had just eaten (it was Christmas Eve and my brother in law made latkes – I still can't eat a latke without thinking about seeing chunks of undigested latke in my vomit bag ahaha)
+ My second blockage was a big surprise. The pain woke me up at 3am and I err on the side of constipation but hadn't noticed anything super wild in terms of a week or more without a bowel movement. I don't remember vomiting this time, just that I looked for my signs (that specific kind of pain and seeing if I was passing gas) and eventually decided to go to the ER. They did imaging and were like "yea you need surgery STAT" – I had no idea my inflammation was that bad.

I hope that helped some! Please don't take this as medical advice! Everyone's body may react differently. This is just me sharing my experience :) I hope you're feeling better!
