Knoxville (WVLT) - Migraine sufferers quickly learn what triggers their headaches, and do their best to avoid those things.
But researchers say there is one trigger you can not control.
A new study shows the weather and temperature change can cause migraines.
Researchers looked at seven years worth of emergency room records and found that more people came in complaining of headaches, when there was a significant change in the weather.
