Headaches usually are brief and can be caused by many things, including too little sleep, eye strain, stress, sinus infections, or a bump to the head. Some headaches last longer and come with other symptoms. Very rarely, headaches can be a sign of something serious.
Signs and Symptoms
The two most common types of headaches in kids and teens are tension headaches and migraine headaches.
Of a tension headache:
a feeling of squeezing or pressure around the front, sides, and back of the head
Some types of headaches can be prevented by avoiding certain things that can cause them, such as getting too little sleep, certain medications, not drinking enough fluids, and using the computer or watching TV for a long time.
