Hi. My brother has been ill for about 3 years now. He has been to a few doctors & no one seems to know what is wrong with him. He has a lot of symptoms. A list of some of them: breaking out in a rash, sensitivity to smells, becomes ill whenever he eats ( he only eats a couple of things such as beef liver & bread), severe stomach pains, migrane headaches, bloating, depression, sensitivity to light & sound, etc.... He does have diabetes but it is fine & glucose is under control. Any idea what could be causing this? He was always very fit & healthy. Then out of nowhere he became ill with whatever this is. I'm very worried about him. Any help/advice, would be greatly appreciated. Thank you.
