While enduring a splitting headache, a person would likely find it difficult to engage in their daily routine, whether that’s at home, work, or school.

This article will review the symptoms, causes, and treatment of a splitting headache. It will also discuss when your splitting headache may be a sign of something serious, warranting immediate medical attention.
