vagus nerve and Angina

I think there is a correlation. My gastritis/gerd shows up in burning upper back pain that sometimes radiates to my jaw! Very scary considering those are heart attack symptoms as well. But I have read that it does have something to do with the vagus nerve like you said. Maybe someone else can help you more about it but I am pretty sure these symptoms surely can feel a lot like a heart attack.

I've posted many times on the vagus nerve connection, and you can search the old messages by putting a few words in the search box at the top of the page. Try "linked angina" or "cardioesophageal reflex." You can google the terms for the scientific papers.

I have had tachycardia and angina incidents for many years that were brought on by my esophagus and stomach not tolerating certain foods. My stomach would churn after eating certain things, and then I would have reflux or heartburn. After that I sometimes developed a rapid heart rate (tachycardia) and chest pain. My allergist had me keep a food journal with times, what I ate, and symptoms. I usually react in half an hour to two hours. Other people, who have migraines, can have a reaction as much as two days later.

I found my food triggers: gelatin, corn starch, many prepared foods, maple syrup, and several medicines, plus a lot more. I googled a few of them with food allergy and found all my triggers contained sulfites. This is not the only trigger that is possible, so don't assume you have the same one unless you have problems with the same foods!
