I haven't had a recurrence of the horrid spinning effect, but I've been mildly dizzy for almost 3 weeks now. Worse when I lie down. Disappears completely when I'm riding a bike (which is an effect I've noticed before when I've had ear grot - I assume that bicycle riding is inherently about learning to use torque from the handlebars for balance rather than what your vestibular system is telling you). Reading (especially from something held in my hand, rather than a screen in front of me) makes me mildly travel-sick, I need some light on to not fall over when I get out of bed (which has been annoying barkata), and I feel a bit unsteady in the shower, but that's the worst of it.
I've been trying to ignore it and hoping it will go away, on the basis it might be viral labyrinthitis or similar.
