External compression headaches can occur when anything worn on your head puts continuous pressure on your forehead or scalp. Symptoms: The pain of external compression headaches is often described as moderate, constant pressure. It hurts most in the area where the object is pressing on your head. As long as the headwear is in place, the pain may get progressively worse. Treatment: To end your headache, remove the headwear that's causing the pressure. Further treatment is rarely needed. If you have a history of migraines, wearing tight headwear may trigger an attack that requires migraine medication for relief. Epidemiology: According to the CDC, approximately 2.5 million TBI-related emergency department visits, hospitalizations, or deaths occurred in the United States in 2010. The following annual statistics from the CDC also apply in the United States. TBI contributes to approximately 50,000 deaths. Approximately 475,000 TBIs occur among infants, children, and adolescents aged 0-14 years. About 80,000-90,000 people experience the onset of a long-term disability due to a TBI.
