Bending over/headche: The only time this happened? Where you bent position for a long time? Bending decreases venous return ( or blood) to the heart; standing up afterward requires more blood to head due to gravity, therefore dizzy.Unusual heart issues like valve stenosis / asymmetric hypertrophy/pulmonary HTN and abnormalities like ArnoldChiari, spinal dysfunction, dural leaks may be unmasked Follow with doc
