the "physical symptoms" I am referring to:

periodic hot-flashes/fever-flashes

a sort of burning sensation in the veins/arteries in the neck, back of the head, shoulders, that general area (and the specific feeling/sense that that burning is a foreign intrusion of the immune system)

The rest of the symptoms are not perceived as physical, but contribute to the physical sensations, which are:

The inability to divert psychic attention from fear-inducing stimulus regarding Ebole

The overwhelming urge to discuss the Ebola "threat" with friends/family
