My wife is 59 yrs old, an avid walker but slightly overweight. She keeps having pains in the area of her diaphragm area of her chest. She can tell a little before she has an attack. She has seen several doctors with no results. They have EKG d her! No noted abnormalities. She thinks it is her Vegus Nerve, the doctors discount it and try other tests. We have had to take her to the emergency room 3 times in the last year because she felt like she was having a heart attack. Is there a test to see if it is the Vegas nerve and if so how do you treat it? Thanks, Dale Cragg
