It sounds to me dear as though you have a concussion. I want to believe that you did go to the hospital for this right? The brain is composed of soft, delicate structures that lie within the rigid skull. Surrounding the brain is a tough, leathery outer covering called the dura. Within the brain are (cranial) nerves that are responsible for many activities, such as eye opening, facial movements, speech and hearing. These nerves carry and receive messages that allow the person to think and function normally. There are also centers that control level of consciousness and vital activities, such as breathing. The brain is cushioned by blood and spinal fluid. There is very little extra room within the skull cavity.An injury to the head causes the brain to bounce against the rigid bone of the skull. This force may cause a tearing or twisting of the structures and blood vessels of the brain, which results in a breakdown of the normal flow of messages within the brain. The damage to the brain generally is found deep within the brain tissue. Because of this damage, the normal function of the brain signals are interrupted.The signs and symptoms of a concussion include severe headache, dizziness, vomiting, increased size of one pupil or sudden weakness in an arm or leg. The person may seem restless, agitated or irritable. Often, the person may have memory loss or seem forgetful. These symptoms may last for several hours to weeks, depending on the seriousness of the injury. Any period of loss of consciousness or amnesia of the head injury should be evaluated by a health-care professional. As the brain tissue swells, the person may feel increasingly drowsy or confused. If the person is difficult to awaken or passes out, medical attention should be sought immediately. This could be a sign of a more severe injury. If you have not already, please see your doctor if you have or develop ANY of these symptoms. I am including a link for you to find more information on this, Good Luck to you, and see your doc soon!
