Background - I have diagnosed autoimmune issues, in particular Ankylosing Spondylitis ("AS" .. in remission). Associated with AS are some gut issues like Crohn's disease, inflammatory bowel disease and ulcerative colitis. I am not diagnosed with the gut issues but I suspect maybe some mild form.
In my case sugar and alcohol generally make the itch worse, especially at night. However eating kidney beans protects me from both.
