Vagus nerve/ stomach issues

For years now I have gotten a mild UPPER backache that is intermittent. It seems to extend to front in ribs or intestinal area. I remember someone years ago from this site saying it seemed like a vagus nerve issue because the vagus nerve extends to stomach area. I also have ibs. This problem mainly comes from back to front not vice versa. It is also UPPER TO MID BACK & NOT LOWER BACK. Can anyone refer me to info on vagus nerve issues? I would appreciate a response as soon as possible. Thank You. Tweet
