I have raynaud's, what can I do to improve my circulation?

Avoid cold; try meds. 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.
Several. Stop smoking stay warm wear gloves use meds- anti spasm vasodilator in general, your vessels are open just spastic.
