Here is some info for you, not sure if it will help, but it might provide some direction:
1. The esophagus is innervated from T5-T10. Is the atlas subluxed, are there any vertebrae subluxed in those areas, etc.
2. It is innervated by the vagus nerve parasympathetically and the 5th cranial nerve (Ophthalmic branch of the Trigeminal). Is there any impingement there?
3. It reflexes to the brow and eyelid. Just like when you get a headache from eating cold ice cream!
4. With EE, there is a large number of eosinophils (white blood cells) in the blood and tissues. This causes inflammation! GERD, asthma and allergies are some of the symptoms. A lot of the time, the esophagus is the branch of this issue and the dysfunction is coming from the lungs, small int and stomach. I would look into food intolerances, bacterial, parasitic and fungal infections (found through labs), start with the foundational HCL principles, as well doing the 4R Gut Healing Program.
