Hi @jenguin37, welcome to Connect. I'm sorry you're going through such difficulties with your abdomen. I can understand how you must be at the the end of rope by now. Scooping out your insides though, yikes! Have you been to any large teaching hospitals for second opinions?

Feeling chronic pain is tough enough, but adding the fact that testing is showing no evidence of why that pain exists is frustrating - been there, done that. I don't have experience with abdomen surgeries other than having an appendectomy, however, I learned that the residuals of surgeries can sometimes lead to central sensitization whereas even once an acute issue has been resolved, there remains pain from central sensitization.

Here's more about Central Sensitization Syndrome (CSS):

Mayo Clinic's Dr. Sletten on CSS -

CSS is all I can think of regarding your unfortunate abdomen history and circumstances. My health journey and experiences with chronic pain that could not be explained or proven through diagnostic testing, is what lead me to learning about CSS and working with Mayo's Dr. Sletten. It might be worth checking out for you. Thinking outside the box, maybe??? I look forward to hearing back with your thoughts. Is it possible CSS resonates with your situation?
