War veterans who suffer from post-traumatic stress disorder (PTSD) may also be more prone to migraines and tension headaches. A study of 308 veterans by researchers at the University of California, San Diego, found that those with physical injuries had more than twice the risk of recurrent headaches as people who were not injured. However, those people with PTSD were four times more likely to get headaches. Physical injury was linked only to migraines, whereas PTSD was also linked to tension headaches as well.
