question: Hello, My name is Robert. My Step son is a spina bifida patience and has a shunt installed which has been revised about 7 - 8 years ago. He has been having headaches for several days and was administered into the hospital and has had CT scans and X-rays performed as well as blood work done, with no signs of problems being shown. Before we administered him we tried Advil, Tylenol and Migraine meds that did no good. Now after him being here and being treated with Hydrocodone for 3 days and still no answers from the Doctors, his headaches have gone for about 18 hours. He is scheduled for another CT this afternoon to see if any changes are noticeable from the previous scans. My question is it possible that the absence of to much CF causing or possible causing these headaches and if so why now is he back to normal with no meds at all ?
