I had a partial SBO in December that put me in the hospital for a couple days. I had major fear of food for awhile after that. They think mine are due to adhesions from prior surgery though. I have a CT scan with Dye at the end of this month with mayo, which is supposed to show if it's from adhesions or something else. I have met with the GI doc at Mayo and that is who is sending me for the scan. I have also met with the nutritionist to learn what foods to avoid etc. I have not had one since, Thank God, but I am very careful about what I eat. Also if I start feeling like I am going to have another one I stop eating and do clear liquids for a day. I also take a teaspoon of olive oil daily which has helped me stay regular. I was having to use miralax and was still struggling. I told my nutritionist about the olive oil and she said she has heard others say the same thing and if it works for me then it is ok. I also found some research on it and they did some tests and learned that it does help with SBO.
I have not had any kind of endoscopy or colonoscopy and that has not been brought up yet. But I am still sort of new to this myself. I'm so sorry you have had to join this club and I hope you find answers. I can say joining mayo and these conversations helped reduce my anxiety about it all.
Ps it took a couple weeks for my soreness to go away completely after the blockage
