Hi Dr. Grief, I recently went for a laser treatment (1st time) they put me on a jiggling machine afterwards, and when I got on it she turned it on and it jarred my whole body, but immediately felt in my head. Was ok after, but had trouble sleeping that night and woke with a mild headache, that Ive had pretty much since. stomach is mildy nauseated, but still have appetite. Could something have jarred in my head to cause this? I am extremely healthy, weigh 115.
