HI! I am newly diagnosed with SLE, but I have had Raynaud's since I was a young girl. Back then I was told that it was from frost bite, but a few years back I finally learned that it was Raynaud's. My fingers and toes turn white and ache when exposed to cold, air conditioning, going into a freezer, etc. Sometimes stress will also cause them to turn white. After they start to warm up, they turn a purplish/grey color. That's when they tingle and I start to get the feeling back. It can be very annoying, especially in the summer, cause you could have on a pair of shorts and tank top, but if you go into air conditioning, on goes the gloves. Oh well, who cares what people think. They don't have to live with the pain. My doc has given be a channel blocker (Norvasc) to help with the circulation. That seemed to help alot. I was even able to go off of it during the summer months, although stress and air condition would always cause a flare. I find using hand warmers, they come in a package that you tear open and shake and they warm up, are extremely helpful. I put them inside my mittens and my boots. I hope this iformation helps a little bit! Have a good night and stay warm!!!
