The 'Types of Headaches' diagram meme originates from a medical illustration commonly used to depict different kinds of headaches and their typical pain locations. The image features four side-view silhouettes of a head, each with red shading to indicate the area of pain: migraine, stress, hypertension, and an unnamed fourth type that humorously covers the entire head in red. This image entered meme culture due to its stark, relatable depiction of overwhelming headaches, which many people experience but struggle to describe. The meme takes a comedic turn by applying the fourth head's total redness to situations that feel overwhelmingly painful or frustrating in everyday life.
