I am a 63 year old white male in good health. I went to my doctor with sevier pain on my left side and he immediately diagnosed me with diverticulitus. No hands on, no test or x-ray or ultrasound. He said to avoid eating seeds, nuts and fruits and vegitables with skin. He also said to take Miralax daily to avoid constipation. I have followed thse directions and do feel better. Since that doctor visit, i have researchd Diverticulas on line and the items listed above seem to be old ideas . I am told by lay people that it is a virus and no change in diet is necessary. What is the real story and is there anything to do to make sure the pain doesnt come back?
