That's because of the overwhelming large number of types, causes, and circumstances of headaches. Tension headaches are triggered by either an emotional or physical stress to the body. When we strain our neck muscles or become overly excited for long periods, certain proteins and enzymes in our body become out of balance. This imbalance is what causes the headache. Most tension headache are therefore easily treatable with over the counter drugs like aspirin or Tylenol.
Sinus headaches are perhaps the most mis-diagnosed type of headache.
They are caused by an inflamation of one of the sinus cavities found in your skull. Common symptom include facial swelling, nasal blockage, and tenderness over the sinus. But the presence of a fever is often the best symptom for diagnosing the headache. Sinus headaches can be cured with allergy medicine or other decongestants which lessen the pressure and infection. Vascular headaches are a group of headaches caused by irregular blood flow.
