If they exist shortly after the injury and continue to improve, then the chance of serious head injury is reduced. In many cases, there are small injuries within the brain that are not found with typical studies. These can cause prolonged symptoms such as headaches, memory loss, confusion and fatigue.

Unfortunately, there aren't usually symptoms of high blood pressure until something serious happens.
Many people walk around with high blood pressure unknowingly.
The best way to know if your blood pressure is high is through measurement, not symptoms. Sometimes, when blood pressure is very high, symptoms can occur. These include headache, trouble breathing, and problems with vision. Other conditions that are associated with chronic high blood pressure include strokes and heart attacks. Therefore, there is good reason to have blood pressure checked and to control it if it is too high.
