of the stomach? Could there be nerve damage from the stomach acid?
About 10 years ago, I had the exact same symptoms. Except back then, the pain was extremely severe and I had lots of white and yellow mucus in my stool with occasional blood. Since I was only a teenager, I wasn't able to articulate my symptoms as well as I wished I could. The doctor just thought it was something else and now it's much worse.
I also have several mineral deficiencies (iron, zinc).
Is there any way to find out for sure if this is or is not a an acutely perforated ulcer and/or abdominal nerve damage?
Welcome to the gastroenterology community! This doesn't sounds like an acutely perforated ulcer or abdominal nerve damage to me. I would recommend you see a doctor about this.
