Shunt boy,
I had my 7th revision in July and ever since then I've had horrible headaches. The shunt was moved from behind my right ear to the top of my head. I went 34 years with no headaches (except when they clogged) to headaches EVERYDAY. It has gotten so bad I sometimes have to take time off work. I'm going to my neurologist for some testing today. I hope your problem got fixed.
