Autonomic Nervous System Question.

I am 16 years old and had my physical today, and one thing I asked was that often, my arms and legs turn red-purple-ish and are often colder than the rest of my body. He advised me to stay around warm temperatures and not to spend extended amounts of time in the cold. I live in Florida, so that isn't a problem. My palms and feet also sweat excessively. My doctor said that the discoloration is due to bad circulation with leads to the Autonomic Nervous System. I did some research on it and my Autonomic nervous system is linked to many, many things. This alarmed me somewhat due to the fact that it is apparent something isn't right. I'm just wondering if this will effect other parts of me, or is the constriction of the vessels on my limbs just bad luck?

Normally, with the Autonomic Nervous System (ANS) disorders, there is a lack of sweating.  There is also something called Raynard's Syndrome that can cause bluish fingers and toes.  It appears there might be a circulation problem, but I wouldn't jump to the conclusionof something wrong with the ANS.  I think a consult with a Cardiologist or Neurologist woukd be best.
