From the history given by you to us we could think of this problem as post traumatic or post concussion headache. The age is not clear though whether it is 26 months or 26 years. Mild injuries of the brain are characterized as a concussion or a brief disturbance of brain function causing loss of consciousness or transient difficulty in thought processes.The clinical features of post traumatic headache may vary from one individual to another. These headaches are typically a steady ache affecting both sides of the head and occurring daily or almost everyday. They are of slight to moderate intensity but intermittently, upon this base of low grade headache bouts of severe or moderately severe headache may occur and these often are similar to, if not identical with migraine.post traumatic headaches also experience other symptoms of the post traumatic or post concussion syndrome. There may be other neurological symptoms such as dizziness, ringing in the ears, vague blurring of vision, psychological symptoms occur such as depression, anxiety, personality change, disturbance in sleep and impairment libido.The people with post concussion syndrome have changes in their mental functioning, primarily difficulty in concentration, inability to work efficiently and associated difficulty maintaining attention and retaining memory. Seizure attacks are not uncommon (supposing the seizure attacks have started after the injury). The treatment of post traumatic headache, as well as other features of the post traumatic syndrome is symptomatic. That is each symptom is treated individually because, unfortunately, there is no medication that will alter the underlying disturbance in the brain.
