This feeling also sent me to the ER once, vibrations caused anxiety, paired with a headache and genetic heart issues already, pushed me to the ER. Nothing was wrong after many tests, so I then followed up with all my other doctors. The only thing found were metabolic issues such as low iron, low vitamin D, low B12. Once I started regularly taking vitamins and stopped alcohol intake, the vibrations calmed drastically. They only happen every so often now, not every day like before.
