The problem with reading online is that you do not get a sense of what is more and less likely. Whether many possible explanations for big chest pain
that is positional, the most likely is acid reflux
. There is a tube from the stomach to the mouth called the esophagus. In order for the stomach to digest food must make quite a bit of acid. Sometimes that acid can bubble up into the chest area via the esophagus. Occasionally people go to the emergency room thinking they're having a heart attack
and it's really an esophageal spasm or and or acid reflux. I would recommend that you take a few times next time this occurs and see if it's beneficial. If it is you may want to start with eating smaller more frequent meals with a low carbohydrate
content. You should avoid eating and immediately laying down.
if this is beneficial I don't think you have much to worry about. If this does not help then it is going to be time to see a medical doctor
