Hi welcome to Health care magic forum. 
                                            Thanks for asking a question to H.C.M.F.
                                            Bloated, fltulence, rumbling stomach,pain under the ribs. 
Nausea after eating, itching and 
joint pains, no relief after all tests, and all systems of medicines. 
                                            Pain under the ribs usually suggests 
stomach irritation, liver and 
gallbladder problems, pancriatitis, lactose intolarance, worms in the intestine etc. 
                                            
Diverticulitis related with gluten diets will be situated in the sides of stomach. 
                                             I advise you to be calm and quiet as the 
anxiety, and tensions may cause gastric disturbances. Practice yoga, 
meditation, reading books, and hearing music. 
                                             Try to have bland foods like bread, and anything with out spices. 
                                             Avoid taking spicy foods, junk foods, and oily foods.Try to avoid milk and milk products.  
                                             Wishing for a quick and complete recovery. 
                                             Best wishes.
