We hear a lot about concussions and professional sports, but concussions can also happen in minor sport and rec leagues. Today scientists are actively trying to determine the optimal way to recover from concussions. We tend to associate concussions with head trauma, like in hockey or football but don’t realize that concussions can occur without head trauma. If you are playing any sport and experience ear ringing, headaches, light sensitivity, blurred vision, irritability, changes in sleep patterns, or difficulty focusing attention or concentrating, you may have a concussion. If you notice these symptoms in yourself or someone you know, get assessed by a doctor.
