These symptoms are part of the post-traumatic stress that may occur after an earthquake.
Additionally, this could last about three months and disappear over time. Feeling dizzy after an earthquake is related to the perception in the brain, as the ear, which is the organ responsible for sending signals of movement and balance, is altered.
This happens because the brain works based on the body's sensations, but since the eyes, which work together with the ears, do not perceive movement, the brain sends incorrect signals to the entire body, primarily affecting balance.
I'm a nautical skipper, although I haven't driven for years since I've lived here. An ENT doctor has prescribed me some daily exercises to improve my symptoms.
Well, maybe my mind doesn't forget (for now) that moment of the shaking ground because I automatically thought of my son, who was at school, and I panicked for a few seconds thinking about what might be happening in that school building.
Indeed, later he told me that the building of his school was shaken, and at that moment my mind broke. I am still thinking about it.
