 Headaches are a common cause of pain and discomfort in people with MS. It may even be an early sign that someone may have MS.

small 2016 studyTrusted Source from Iran found that individuals with MS have headaches more frequently than those without this condition.

A small 2017 study found that 78 percentTrusted Source of people in the study with MS reported headache pain within the last 4 weeks.

The types of headaches in the study varied, but about half of the participants with MS in the study stated they had throbbing or pulsating headaches.

About 30 percent of the study participants reported sharp headache pain, and 28 percent said they had dull or tension headaches.
