For 23 years I went thru pain .Went to many Doctors trying to find out what was wrong.In October of 2009 I was hospitalized for open heart surgery. Well they found my Aortic valve was failing. Had an As sending Aortic Aneurysm, an also needed a triple by pass.While I went thru the dozens or so of MRI's an CT's. Now at 53 the heart problem was enough. But no while doing a scan of the brain. They found I was over shunting. So after goin to a neurosurgeon .He looked at my scans, an said he could not see anything wrong. Two weeks later went to the hospital for extreme dizziness,and loss of vision in right eye. After another CT they found my ventricle was smaller than last time. So this time I went back to the same clinic, But asked for another doctor this time. A new vp shunt an still pain. I am at the point of giving up. It is like the Doctors are to busy to see someone who might really sick
