Discussion: Why are migraines considered an unbearable pain?

Migraines can last for consecutive days, during which the patient has difficulty sleeping and functioning, even watching television. In acute migraines, concentration is impaired, a car can not be driven, especially at night, and the patient sometimes prefers to rest quietly. As someone who suffers from many complications of cirrhosis, I can attest that migraines are a crippling pain.
