Here is a good description of head aches.


Tension Headaches — Tension-type headaches often feel as if your head is being squeezed by a vice at your temples — the sensitive spots at the side of the head between your ears and eyes. A decrease in tolerance for stress, decreased thinking efficiency and reserve, and depression are often associated with tension headaches.

Migraine or Neurovascular Headaches — Migraine headaches account for approximately 20 percent of PTHA (although many practitioners will debate this). Migraines are thought to be the result of changes in the blood flow inside the brain. The risk for migraines post-injury appears to be strongly genetically linked.

Cervical/Cervicogenic Headaches — This kind of PTHA is common after a brain injury and is usually related to neck injury involving ligament, muscle, and/or joint (facet) injury.

Musculoskeletal Headaches — Musculoskeletal headaches are often overlooked but are quite common after a TBI. Pain in the muscles or bones of the head, neck, shoulders, and/or jaw (see below) can be a source of head pain.

Temporomandibular Joint Disfunction — TMJD sometimes occurs after trauma and involves injury to the "chewing" muscles around the jaw, or to the jaw joints themselves leading to headaches typically experienced on the side of the head in the temple region(s).

Neuritic and Neuralgic Pain — Injury to the nerves in the scalp or larger nerves in the face (e.g. supra-orbital) and upper neck (e.g. greater occipital) from the trauma can result in head discomfort as well as headaches that may present with numbness, sensitivity, and/or shooting- or stabbing-type pains.

Here is another head ache type. Low blood sugar head aches:
What Does a Headache Caused By Hypoglycemia Feel Like?
Headaches from hypoglycemia are usually described as a dull, throbbing feeling in the temples. The pain can occur with other hypoglycemia symptoms, like blurry vision, increased heart rate, nervousness, fatigue, irritability, and confusion. Hypoglycemia can also trigger a migraine headache. In fact, some migraine sufferers report craving carbohydrates before the migraine hits, which may be the body’s way of regulating blood sugar and preventing the headache. Migraine headaches caused by hypoglycemia will usually not be accompanied by typical migraine symptoms like nausea, vomiting, and sensitivity to light and sound. Instead, the migraine is more likely to be accompanied by the hypoglycemia symptoms noted above.
