Mal de debarquement presenting in the Emergency Department.

Mal de debarquement (MDD) is a common, benign, and self-limited syndrome suffered by many people after disembarkation from an oceangoing vessel. It is characterized by a continuing sensation of being on an unsteady pitching and rolling deck, even after a return to solid ground. Symptoms typically dissipate over several hours or days, but can linger for weeks.
