Gail, In looking up Raynaud's Disease, I came across an article titled, Raynaus's Disease, Too Much of a Good Thing. This doctor made a distinction between primary Raynaud's Disease and secondary Raynaud's Syndrome. Which does your doctor think you have. It seems the types of treatment can differ between the two. Keeping the body warm is done for both, but there are differences after that. I think trying to discover the exact cause of the disease or syndrome would be the most difficult, as so many things can cause it.
Even playing the piano!!!Rolled Eye Take care and let us know what your doctor suggests. Oh, Stress is mentioned in one article as a cause so relax already.
Take a long walk. Or you can use a technique that Harpmaker and I use, which is to get someone to give you a back rub, then rub down the arms pulling gently until you reach the fingers. Stroke across the back of the hang pulling the fingers of the person giving the backrub down through the fingers of the person being rubbed. and literally pulling the stress gently out of the finger tips. I don't know if this makes sense all I know is that it works. I'll get Harpmaker's arm completely relaxed and stress free just by these long gently pulling movements down the arm, over the hand and fingers. The tension just flows out through the finger tips. Take care. FF.
