A week ago I went to the er for Vertigo I guess I was sitting down and the whole world was spinning crazy fast. After 20 mins it stopped but I was nervous so went to the er. They didn’t really know what caused it but my ekg looked normal. After the spell I got a weird static like vibrating headache. Today it happened again except nothing spinning just very dizzy like and light headed. Got the same headache after. Has anyone had anything like this before? My glucose was fine and my ekg.
