Migraines can kill you if they are caused by something more serious than just a normal headache or stress.
In rare cases a migraine can be caused by a brain tumor or other serious health issues so if your migraine does last longer than a few days or is constant and gets worse then see a doctor about the migraine.
Most migraines are just caused by stress, loud noises or just other simple things.
If you take some pain medicine such as Tylenol or Aspirin and the migraine goes away then it's likely nothing serious.
But if the migraine does persist then it could be something more serious.
Having a severe migraine that comes on suddenly and gets worse or doesn't go away within a few days may be a sign of a brain tumor or brain cancer.
So always get checked out if you have a really severe migraine.
