I was involved in a car accident 3 years ago, and have been diagnosed with PTSD, severe mild traumatic brain injury, suffer from cognitive issues, being able to find my words Express what I m trying to say, focusing.... neck shoulder and back pain, vagus nerve dysfunction affecting colon. I am not able to have a bowel movement without taking several products. I am wondering about the vagus nerve affecting the eyes? I have a lot of head pressure and eye pressure especially the right eye. Is there a connection? If so can you explain what it is? Thank you Lorraine
