A person suffering from a concussion may become rather sensitive to the sounds, especially the sudden and loud ones. Sensitivity to light often means a patient may experience some issues with the surrounding sounds as well. It is the consequence of the damaged auditory system and bran. Even without anything going on around, the patient might hear some ringing or ticking sounds in his head, which simply drives mad from time to time.
A feeling of ongoing fatigue is one more obvious symptom of a concussion. It makes sense that a person who hears some noise all the time, lacks healthy sleep, is confused, dizzy, and irritated is overly exhausted. He or she feels like working all day long doing some difficult physical tasks. Oversleep is one of the outcomes of constant fatigue. However, taking an extra sleep usually does not help. Any head trauma or shaking end up fatigue. It is better still to avoid oversleeping.
