Your headache pattern can often act as a biological clue that points toward what may be happening in your body. Headaches are generally divided into primary types, which are conditions on their own, and secondary types, which are symptoms of another underlying issue. The location, intensity, and accompanying symptoms can all provide useful hints about possible causes, although they are not a substitute for medical evaluation.

Tension-type headaches are the most common and usually feel like a dull, tight, or band-like pressure around both sides of the head. These are often linked to stress, fatigue, poor posture, dehydration, or tight muscles in the neck and shoulders. They tend to build slowly and can last for hours or even days if the trigger is not addressed.

Migraines, on the other hand, typically cause a stronger, throbbing pain that is often focused on one side of the head. They may be triggered by hormonal changes, certain foods, lack of sleep, or sensory overload such as bright lights or loud sounds. Migraines are also commonly accompanied by symptoms like nausea, sensitivity to light, or visual disturbances.

Cluster headaches are less common but extremely intense, usually centered around or behind one eye and occurring in cycles. Sinus-related headaches tend to create pressure in the forehead, cheeks, and nose, often worsening when bending forward and usually linked to congestion or infection. Dehydration or caffeine withdrawal can also cause pulsating head pain throughout the head. If a headache appears suddenly with extreme severity, or is accompanied by confusion, fever, stiffness, or weakness, it should be treated as urgent and medically evaluated.
