When I was 6 years old, when we would stop at a gas station, I could smell the gas and I'd get a headache with vomiting, etc. My parents said I was getting car sick from riding in the car. Perfumes were a trigger, also. Instead of migraines, I was diagnosed with sinusitis. Not until I was an adult, and diagnosed with migraines, did I get help. What migraine symptoms did you have as a child?
