See, some of your list of problems has to do with where the nerves go from the
spine, which the ones affecting your hands and fingers and thumb come out
of the cervical
spine, and then the ones affecting your blood pressure and breathing and the pain between your shoulder blades come out of the thoracic spine, normally T-5 and above, which T-4 is about where the actual nerve injury is since it's always felt one vertebra down at T-5.
