Raynaud's Syndrome
"the past several winters the tips of some of my toes turned black and were ice cold , but would return to normal when the weather warmed up. I had tests done at a vascular specialist and had some diminshed circulation to my feet but nothing that required any type of surgery . I was prescribed Nefedipine and within a week or two my toes returned to normal and my feet were much warmer . I only take this drug during the colder months"
