My GI specialist told me that my food is not digesting and that is still in my stomach from the night before and that he believes my Vagus nerve has been damaged from 2 prior Nissen surgeries. I hurt after I eat and cramp up and get nauseated. I have problems going to the bathroom also. I am at my wits end with this. This has been going on for at least 3 years. Is there anything I can do?
