My best NYC chiropractor shared his knowledge about childhood concussions and he said that if your child have experienced previous head injury, are taking a blood thinning medicine, suffer bleeding disorders, are under one year old, have other neurological problems, have difficulty walking or are active in high contact sports. If your child is harder to wake up than normal, shows worsened symptoms, won’t stop crying, doesn’t eat well, has worsening headaches or symptoms that have lasted longer than six weeks, then contact your doctor or caregiver. If your child shows a change in personality, bleeds out of the ears or nose, has trouble recognizing people, or vomits repeatedly, go to the emergency room. For seizures, unequal pupil size and longer-term unconsciousness, dial 911. Irrespective of advice you get on the internet or by phone, if you have any doubt in your mind about your child’s health after a head injury, seek the help of a professional. You know your child best!
