I know my acquired brain injuries make me a little different. Not the only thing believe me

However, when I eat, I feel the pressure on my spine shooting into my head. My concussion was very mild so virtually all symptoms are from ABI.

On one of my ABI's, It literally felt like something shoot from the top of my head down spine into tailbone, and have had pain ever since.

Does the eating put stomach pressure on the damaged spine and shoot it into head? And how did the damage come about in the spine with an abi.

I know, I should go ask a doctor Just trying to get some comfort

Well, an injured brain can send out all sorts of weird signals. That said, there are things, other than ABI, that can be felt as referred pain in the back, during eating. Some example are ulcers, gallbladder swelling and pancreatitis.

Like you said, you will probably have to talk to your doctor.
