I have what is considered a "wastebasket diagnoses" called Migraine Associated Vertigo or MAV, for short. The most disheartening thing I have been told about this condition is that there is no cure, doctors don't know what causes it and it's only a disease that exists out of exclusion of other more structural abnormalities or findings. That's quite angering to hear since most other illnesses or structural problems are easy to diagnose and treat (i.e. a broken leg). Some doctors also don't believe in my condition. For example, one neurologist denied the possibility of this and instead, told me it was anxiety. My chief complaint is dizziness and imbalance which has lingered after a traumatic time with BPPV (positional vertigo). It's frustrating that a supposed condition can be controversial diagnoses with many on the fence about whether exists and what symptoms must be present for it to be true. In fact, the only way the medical professional can validate this condition is to learn whether or not migraine medication helps the patient. And since we know how effective placebos are, it adds further doubt in my mind. This is very nervewracking!
