Thanks glentag,

By the way, do you know what is the relationship between the CNS and the PNS? Can a simple nerve compression create stress/hyperactivity to the CNS? Are there any studies on that?

--certainly the central nervous system--brain and spinal cord--receives signals from the peripheral nervous system and interprets them, giving rise to the sensations we "feel".

There are situations in which the central nervous system has trouble interpreting unusual signals from the peripheral nerves, such as those associated with axonal damage--it can interpret this as any one of the many positive (pain, tingling, shooting, heat/cold) or negative (numbness/sensation loss) sensations of neural damage. But the same type of damage may give rise to different sensations in different people.

Ever since I have started to have what the doctors I am working with believe is nerve pain in my legs, I have started getting alternating red, burning feet and freezing cold, blue feet. My hands also get red and burn from time to time.

Does this sound characteristic of a circulation issue due to nerve pain in the legs?
