I too have Raynaud's. I've had it since 1983. Also have Parkinson's Disease diagnosed 1/2008. It's been bad this year...having attacks even in the house. I've tried battery operated heat gloves and socks with no luck. Have been buying those little hand warmers (I must have stock in them I buy so many) A doc I know takes the medication (can't remember the name) that treats high cholesterol and high blood pressure and gets great relief. Well, I have low BP so that wouldn't help me. Yes, stress brings it on too. It's a double doozy having frozen parkinson's hands.
