My NS sent me to a Neurologist after my programmable shunt has been re set twice since surgery. Just went today and he is running an array of tests. Maybe they'll all come back clear and they will realize it is my shunt! I keep having headaches. I'm wondering if maybe my body is not responding to the programmable like it did the fixed valve? I have been unable to work due to these headaches. Are you having any other symptoms since the surgery besides the headaches? I'm still having some dizziness and recently problems sleeping. I'm so sorry to hear that you are still having problems. I just have to be annoying and keep calling them. It's crazy!
