Introduction
Forehead pain is a common symptom of infection, inflammation, vascular conditions, or physical trauma. Forehead pain can result from increased fluid (edema) in the soft tissues surrounding the forehead, sinuses or brain. It may occur in conditions affecting the forehead area itself or in association with more generalized conditions such as colds, flu, or low blood sugar (hypoglycemia).

Inflammation and infection are common causes of forehead pain. Infection of the sinuses (sinusitis) can lead to forehead pain. Meningitis (inflammation of the sac that surrounds the brain and spinal cord) also results in forehead pain. Trauma to the head may cause forehead pain and can indicate a serious or life-threatening condition. These traumas include concussion, intracranial bleeding, and subdural hematoma.

Common causes of forehead pain include migraines, vascular headaches in which pain may occur on one side or the entire forehead. Forehead pain is also commonly caused by tension headaches due to stress or muscle tightness in the neck, jaw or scalp. Other causes of forehead pain include eye strain and withdrawal from substances such as caffeine or alcohol.

Sudden forehead pain accompanied by numbness or weakness of the legs, especially when it occurs on only one side of the body, can be a sign of stroke, meningitis, intracranial hemorrhage, or subdural hematoma. Seek immediate medical care (call 911) if you, or someone you are with, experience these symptoms.
