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.
In all the vascular headaches, the blood vessels in the brain either shrink or become enlarged. This results in either too much or too little blood to the brain. Either way, your brain shows you something is wrong by creating the pain of a headache. Ice cream headaches are triggered by eating ice cream or other cold food item too quickly. It turns out that there is a nerve cluster located in the roof of your mouth near the back.
