See a Neurologist: Head injuries can result in long term headaches, memory problems, seizures and pain depending on the brain region involved and the severity of brain damage. There are a variety of neuromodulatory therapies and rehabilitative therapies available for treatment via a Neurologist. They can do a battery of testing to determine what areas are involved and can advise on specific treatments.
