My daughter fell off a 10 feet high dock and hit the water yesterday. She has had prolonged headaches from this. I took her to the school dispensary and the doctor tested her and said that she definitely had a concussion and ordered a CSCAN from the local hospital. The results was no blood around the brain but fluid on the brain which I believe is Hydrocephalus, correct. To prevent this getting any more serious and requiring a shunt shouldn t she lay flat for a day or two? She feels like Life as normal!
