If the answer isn't available here, do a search for DAN, Divers Accident Network, This is a membership organization supported by divers. Many medical problems can be answered by their FAQ. Joining gives you paid medical insurance for diving accidents, and 24/7 access to medical personnel in case of a problem here or anywhere on the globe.
My two cents. . . one of my dive partners has an inner ear problem, that causes vertigo with the pressure change. His family has a history of the same problem. Only after discussing this with a doctor, maybe at DAN, should you ignore this and continue the dive.
