Dr Donald Mangum...I've heard your the "best of the best" from my boss and patient of yours. My husband is having serious gasto problems. He has had alot of tests, blood, stool, CT scan over a week ago. His doctor has not had time to give him any results. Hes been sick enough that it affects his sleep, hobbies, what he eats and drinks. He cant leave the house for long periods of time. I have no idea how to get him in to see you and not sure why I think you would have the answers but I seriously do. Any answers would be better than none. His current doctor, Dr. Stagg in Lowell AR. isnt giving him any information. All he heard from was Staggs nurse who gave her opinion and she said in all her years working for Stagg shes never seen a CT scan like Daves. Now we have enough information to be scared to death. All lymph nodes in his abdomen are swollen...So here I sit typing to you for help!His wife,Ann Harrison
