There are migraine symptoms that may indicate a more serious medical condition. The following is a list of migraine symptoms that require a visit to a doctor:

One:  A very sudden headache that gets progressively worse, and may include nausea, vomiting or dizziness (may be caused by a stroke).

Two:  A spontaneous headache that is worse than any other headache (may be caused by an aneurysm).

Three:  Terrible headaches that start after age 50.

Four:  Headaches that are followed by impaired memory or balance, dizziness, numbness or tingling in extremities (may be caused by a stroke).

Five:  Headaches that get worse with coughing or sneezing (may be an infection in the brain).

Six:  Headache that sets in following an injury to the head (may be caused by a hemorrhage).

Seven:  Headaches that are present simultaneously with a fever (may be caused by spinal meningitis).

Eight:  A pulsating pain around the eye that may spread to the ear or neck and is not alleviated by pain medication (may indicate a blood clot).

If you are unsure as to whether or not your headaches are indicative of a dangerous medical issue or just an ordinary migraine, you should see a neurologist to be safe.
