I experience vertigo like symptoms when overheated, always brought on by excercise! terrible dizziness and nausea that lasts for hrs. I get very red flushed face, I was tested for vertigo and cardiac insufficiency and was told I had what was called a non headache migraine. I was prescribed topirmimate and took it for a couple of hrs however it did not really prevent. Went to a neurologist and was told it was an inability to regulate my body temperature.
What can I ask to be tested for as living with this is not much fun!
