old and had a fall, four days ago, in which I hit my head on a concrete curb. According to the ER doctor, the CT
scan was negative, although he said it showed enlarged lateral ventricles. I"ve been having severe headaches, for 5 weeks, and severe nausea for 7 weeks. Could the headaches and/or nausea be caused by the enlarged lateral ventricles? Just how serious is this condition?
