The disease is termed as "raynauds disease". It is a rare disorder of the blood vessels, usually in the fingers and toes. It results in a particular series of discolorations of the fingers and/or the toes after exposure to changes in temperature (cold or hot). Its exact cause is not known till today but blood vessels in the hands and feet appear to overreact to cold temperatures or stress. However, treatments can reduce the number and severity of Raynaud's attacks. Treatment includes medications like Nifedipine. It works by 'opening up' the small blood vessels and helping circulation. Angiotensin blocking vasodilators block the effects of angiotensin, which is the chemical produced by the body to make the blood vessels narrow.
