Diane - If he gets the slightest inkling of pain, go immediately to the local ER and
DO NOT LEAVE!!! until someone performs tests, even if this means sitting in their waiting room as this can be a life-threatening condition. I do not mean to scare you, well I guess I do. The survival rate of a perforated bowel is not good.
Diverticulosis is when pouches form in the instestinal wall where it is weak. Diverticulitis is an acute attack meaning infection has set in from debris collecting in these pouches such as seeds from strawberries, sesame seeds off buns, etc. Once an infection has set in, medical treatment is necessary.
Praying for him, but God has provided Drs. to help us here along with the healings that He does supernaturally. A clear liquid diet for a few days would not hurt. Broth, gelatin, etc. If you go to Gordon's, you can get the soup bases - the au jus, roasted beef and the vegetable are especially nourishing. Also clear juices such as cranberry, etc. This is what they would give him in a hospital while waiting for a diagnosis as it allows the bowel to rest a little.
Time for me to head for bed.
Goodnight and sweet dreams to us all.
