The vagus nerve is the longest cranial nerve in your body, responsible for controlling various bodily functions such as heart rate, digestion, and speech. It runs from your brainstem down to your abdomen, passing through the neck area. When this nerve becomes compressed or "pinched," it can result in pain and other symptoms that affect your quality of life. https://nurosym.com/blogs/articles/pinched-vagus-nerve-in-the-neck-symptoms
