The most common cause of headaches is scalp and neck muscle contraction. Tension, anxiety, strain, stress, fatigue, and depression may all bring about sudden or gradual muscle contraction and pain.
Migraine headaches are another common type of headache.
Migraines are usually much more severe than muscle contraction headaches. They are caused by changes in the blood vessels and blood flow in the head. Headaches can also be caused by many diseases and disorders affecting other parts of the body, including ear problems, eye problems, jaw problems, sinus problems, arthritis, high blood pressure, nerve diseases, and even tumors. Treatment for headaches varies, depending on the cause. Proper diagnosis is important, so tell your doctor about any severe, frequent, or ongoing headache symptoms.
