Is there a real cure for raynaud's syndrome?

If cause is "cured": Other than treating the underlying condition(s) causing raynaud's symptoms, avoiding emotional stress, keeping warm, not smoking, and avoiding caffeine, some medications can help. Nifedipine, diltiazem, losartan, and prazosin have been used in patients with raynaud's phenomenon, to block vasospasm and/or relax vessels so they can dilate to let more blood flow through them.

No: Raynaud's is a group of symptoms, not a real disease itself, in that there is a single cause. The best management is to have a complete physical exam and blood tests looking for a cause.
