Your diagnosis seems more descriptive than explanatory. I had/have many of your symptoms + more. My current working theory is, or includes, thorasic outlet syndrome.

TOS would provide the pathway which causes these symptoms. TOS is caused by a crimping of the subclavian artery, the artery below the clavicle. Among other things the subclavian artery feeds the thymus and the vertebral arteries in the neck. The vertebral arteries feed the lower brain, including hypothalamus, pituitary gland and visual cortex.

Together the hypothalamus, pituitary and thymus are the brains of the immune system. Backwards displacement of the manubrium causes crimping of the great vessels in patients with thoracic outlet syndrome (TOS):

Good luck.
