I started showing signs of Raynaud’s last winter, and after a reprieve for the summer it came back worse in October. I finally just got an appointment with a rheumatologist. My big question is: Has anybody heard of or experienced Raynaud’s being caused by a single extreme or prolonged exposure to cold? Our nurse at work says that’s how hers was caused, but I’ve found nothing about it in my research. My condition is affecting my work, and confirming (or ruling out) this link could have significant impact on my future.
