Answer to Question 1

Raynaud's phenomenon (RP) involves spasms (vasoconstriction) of the arteries and arterioles of the fingers and toes. The spasms, typically induced by cold exposure or emotional stress, cause reduced blood flow to the area, which leads first to skin blanching (i.e., reduced coloration), then cyanosis (i.e., a bluish color due to lack of oxygen), and finally redness upon reperfusion (i.e., blood restoration) of the digits. Spasmodic episodes may last minutes or hours and may involve burning or cold sensations in the affected areas.

Answer to Question 2

Possible mechanisms include changes in blood flow, the central nervous system, the autonomic nervous system, or neurotransmitters disrupting the migraine's pathophysiology.

People who have myopia, or nearsightedness, are not able to see objects at a distance but only up close. It occurs when the cornea is either curved too steeply, the eye is too long, or both. This condition is progressive and worsens with time. More than 100 million people in the United States are nearsighted, but only 20% of those are born with the condition. Diet, eye exercise, drug therapy, and corrective lenses can all help manage nearsightedness.
