You need to rule out intestinal permeability AKA Leaky Gut Syndrome.
A simple urine test called Lactulose and Mannitol test can confirm this.
It measures the levels of these 2 sugars in urine six hours after ingesting them.
All the scans and tests you had done cannot detect intestinal permeability, something conventional medicine
has mostly ignored :(
It can lead to autoimmune disease, IBS, fatigue, mood disorders, cognitive and learning disabilities, skin disorders...
Jason, you are young and have your whole life ahead of you.
Seek a reputable Functional Medicine Doctor to help you
with this issue, before it develops into something more serious.
Oh, another recommendation is to either do a food elimination diet to rule out food sensitivity or try
Dr Coca' Pulse Test -free download- which takes about a week to complete.
Let me know your thoughts on all this.
Best wishes,
Niko
I have that same thing. It usually wakes me up in the morning and stops after I finally am able to have a bowel movement or have gas.
