In brief: OK?

7% of woman have raynaud's phenomenon.
Most occurs in isolation, but workup is required to assure not part of a larger problem. This does not just mean laboratory studies, but requires assessment by a knowledgable/experienced physician.

In brief: Unknown

This is an annoying condition, caused by the body narrowing the arteries to the extremities when the core of the body temperature gets a little low.
It can be caused by excess sympathetic nervous system activation too. The best defense is to keep warm, wear a hat outdoors, and stay physically active. There are medicines which can help a little too.

Agree with Dr. Point. Also, avoiding smoking is helpful. Red flags to prompt evaluation include spontaneous sores, blood blisters or unremitting severe pain -- these are rare.
