What do you know about Raynaud’s Phenomenon (Quiz of the Day)

The answer is E, and two respondents got it right, but the first to answer get the gift.

Raynaud’s phenomenon is characterised by vasospasms of arterioles and
arteries in the extremities resulting in blanching, cyanosis and numbness. This
is followed by redness and throbbing pain. It is mostly idiopathic in origin and
secondary causes include occlusive arterial disease and trauma. It may be
triggered by exposure to extreme cold and other factors that may cause
vasoconstriction such as smoking. Treatment includes nifedipine because it
dilates coronary as well as peripheral arteries. Nifedipine is useful in reducing
the frequency and severity of attacks.
