Severe vasospasms diagnosis after UE Arteriorgram

I am 28 yrs old -small mitral valve prolapse and w/ 5yr history of cold hands and feet(entire hands and feets-not localized to certain fingers) and premature CAD in both parents sides of family( moms mom died at 38). As of January 08 I began having episodes of numbness and throbbing in arms and legs and feet. I was on Adallat C for 4 months with fairly good relief and at the end of 4 months and was then put on Norvasc. These were specifically for the cold hands and feet, not for high blood pressure, as mine has always been low (90/60). The Norvasc was tried for 30 days with no improvement. Nerve conduction studies ruled out nerve damage so arteriorgram of upper extremities was recommended. My results per radiologist was "Severe Vasospasms" When they injected the dye into the artery they could not see anything. However, when nitroglycerin was administered everything showed up...no blockage. I also have chest pains and shortness of breath and fatigue along with the coldness spreading to my legs along with leg heaviness, cramps and weakness when walking. I have been referred to a cardiologist. What is the treatment for severe vasospasms? Could this mean I am having vasospasms everywhere including coronary vasospasms? Although I am young, does my family history of premature cardiovascular disease warrant other tests to resolve my condition?
Thank you for any help you can give me.

Have you been dx'd with Raynaud's disorder?  Doctors don't completely understand the cause of Raynaud's attacks, but blood vessels in the hands and feet appear to overreact to cold temperatures or stress (vasospasm cause is not completely understood either).. Raynaud's is a condition that causes some areas of your body — such as your fingers, toes, tip of your nose and your ears — to feel numb and cool in response to cold temperatures or stress. It's a disorder of the blood vessels that supply blood to your skin. During a Raynaud's attack, these arteries narrow, limiting blood circulation to affected areas.

To treat vasospasm or Raynaud's is to widen (dilate) blood vessels and promote circulation, your doctor may prescribe:
Calcium channel blockers. These drugs relax and open up small blood vessels in your hands and feet. They decrease the frequency and severity of attacks in about two-thirds of people with Raynaud's.

Alpha blockers. Some people find relief with drugs called alpha blockers, which counteract the actions of norepinephrine, a hormone that constricts blood vessels. Examples include prazosin (Minipress) and doxazosin (Cardura).

Vasodilators. Some doctors prescribe a vasodilator — a drug that relaxes blood vessels — such as nitroglycerin.
