HEADACHES can start for many different reasons. A headache is not a sickness or a disease itself, but a symptom that indicates a possible sickness or disease somewhere in your body.
Severe headaches can be the beginning of pneumonia or infections of the ears, nose, or throat. Others, less severe, can indicate minor infections, allergies, over-tiredness, mental strain, eye strain, or hunger.
All these disorders send pain messages to your brain and the surrounding areas, which are very sensitive. When they "hurt," you get a headache. -
