Even the dizziness. And
stress is not always the cause, there are many triggers...hunger, allergies, aggrevation,
scents...to name a few.
The thing you have to understand is finding a remedy for you is a marathon, not a sprint. There are lots of medications and combos and each person is diff so, just cause one migraine med doesn't work doesn't mean it's not migraines.
As for the bump...was it there when they did the scan??
