Mark,

Should I be concerned that my vertigo (rocking, seasick feeling) is constant and not just when I'm moving around. Even sitting still or laying down I still feel rocking. Could this dizziness be coming from my neck? I've had an MRI done of my neck and it showed nothing abnormal. PT and acupuncture don't seem to help, but maybe I could benefit from an upper cervical chiropractor? Let me know your thoughts, thanks!
