I was shaking all over when i was poisoned, I am normally quite steady. for months after being posioned (it really has just fully gone away the past several weeks, lots of heavy duty chelation), in my ear above the tooth that was drilled down sloppily, it sounded like a distant freight train when I would lay my head on a pillow to go to sleep. Must have been a problem with the nerve there, the rattling sound/sensation. Just sort of disappeared lately, thankfully.
