My electrical sensitivity manifests as problems with cell phones. They give me headaches and electric currents sensations in the head. After having to talk recently over a cell phone for about ten minutes and even though I used speaker phone and kept it couple feet away in front of me, my eyesight became so fuzzy that I couldn't read text on a computer screen for the rest of the day. The eyesight largely recovered after a night of sleep, but it still took several days before all residual effects on the vision faded away.
