UPDATED--im a little nervous

My little brother is in the hospital right now. He's 15, and Im 22, so i feel like hes my kid sometimes. He has had a constant headache for so long, and now they are running all these tests. Im so upset. I just want him home, so that I know he is ok.....sorry girls, I just had to get this off my chest




Thank you to everyone for your thoughts and kind words. The cat scan came back fine, and thankfully, they did not do a spinal tap (that is what I was so concerned about...I know how painful they are) Now he just has to follow up with a bunch of drs to try to get to the bottom of this. Thanks again to everyone!
