Carotid Artery ????

I have read that symptoms for Carotid Artery disease usually show up when it's too late.  I am hypersensitive to my body though and wonder if some of my symptoms could be signs of CAD.  I get strange spasms in my head in place that seem to be where the carotid (left) runs.  I also get numb in my face and neck where my carotid is.  I also hear my pulse in my left ear sometimes and sometimes after I burp, I hear pulsing noises in my left ear.  Should I be concerned about CAD?

Have you seen a doctor for this?  These are certainly symptoms that you would want to have evaluated.  Ally
