Share of Cost, Migraine Headaches
Migraines can run in families and are diagnosed using certain criteria.
• At least five previous episodes of headaches
• Lasting between 4–72 hours
• At least two out of these four: one-sided pain, throbbing pain, moderate-to-severe pain, and pain that interferes with, is worsened by, or prohibits routine activity • At least one associated feature: nausea and/or vomiting, or, if those are not present, then sensitivity to light and sound
A migraine may be foreshadowed by aura, such as visual distortions or hand numbness.
