As previously mentioned, concussion symptoms include depression; fatigue; headaches; light and noise sensitivity; nausea, and trouble concentrating. Signs and symptoms of concussion typically reveal themselves right after a serious injury takes place. Nevertheless, some symptoms are delayed and can show up in the hours and days following an accident. In the aftermath of a serious personal injury, it’s important that family members and your immediate support network provide care and keep a running log of your symptoms. This way, they can be accurately escalated to both a doctor and a Toronto personal injury lawyer like De Rose.
