The wife of my dearest friend has exactly the same symptoms. At first she had some light headedness and then some vomiting. She went in the ER a few days ago and found some clog in the input side of the valve. She is now out of the ER and is sleeping A LOT, even when she wakes up she might say a word or two and then go back to sleep as she is talking to you. Because of this frustration we're now looking for valve alternatives, at least the doctor is open to suggestions. How is your son doing?
I had a Codman programmable shunt placed in 2003, and have experienced extreme fatigue, dizziness, nausea, headaches, etc. to varying degrees ever since, even though mine has been adjusted once, and seemed fine for a while. No one will tell me what my setting is and I can't even get anyone to see me now. EMORY lost my records, and because this last surgery was done in an emergency, the doctor used the Codman, which my doctor doesn't use, or even know anything about. As a result, I am going through HELL trying to get some help. My next step is to call the AMA and a lawyer.I will be praying for your son. I can only imagine how rough it would have been if this had happened when I was in college.
