Hi
I'm new here and I would really recommend a book called "TISSUE CLEANSING
THROUGH BOWEL MANAGEMENT"
I'm not plugging this (whilst available on Amazon, this is actually quite old and available online as free pdf download if you Google search!)
Worth reading, and when you see the xray pictures of diverticulitis condition example (really shocking), the symptoms described matched many posts on this site. After reading and understanding the gut for conditions like this, you'll realise medication alone won't give you a cure.
I have IBSc and took the easy route of taking probiotic as the author described and it eradicated the symptoms I had for 2-3 months in 3 days.
Hope you find it informative
