Could a vertical nystagmus, that happens sometimes early in the morning, indicate something about the symptoms/conditions listed on my profile?

Nystagmus not alone: Vertical nystagmus is a rare neurology sign to begin with but would be extremely rare not associated with dizziness. Nystagmus is what your eyes and brain do to try to catch up to the sense of movement. Congenital nystagmus is the only way i can think of that someone cannot have dizziness/vertigo with nystagmus, but this is usually horizontal.

Nystagmus refers to: An oscillatory but not rhythmic ocular movements and has classically been divided into 2 broad categories based on the clinical appearance- pendular or jerk nystagmus. Important ? Include tempo of symptoms (sx), associated sx, and whether it is monocular/asymmetric binocular, or symmetric binocular oscillations. Both of the medications listed can cause/contribute. You need to talk with your doc.
