Have you considered looking for ER or Urgent Care Clinic work as a med tech? I know a paramedic who moved to ER work for more normal hours.

A disability rating will likely need a complete NeuroPsych Assessment to determine what job functions are appropriate for you. \

How about a school nurse type of position? Or, get trained as a concussion specialist so you can administer concussion tests to athletes for a school district.

Lots of ways you can work while staying away from risk and over-stimulating environments.
