I hate to refer you to a web site, but I got some pretty easy to understand info from the Readers' Digest health site. I don't have the address anymore-it came up on a googles.com search. There's a home remedy that sounded interesting, but I haven't tried it yet. There are 2 kinds, primary & secondary. Primary has no known cause and is the most common. Secondary may develop as the result of other diseases such as lupus, scleroderma, RA, or carpal tunnel (diseases that damage the arteries) Other factors that may lead to it can include vibration from powaer tools, smoking, or frostbite. As usual, women are more likely to get it. Hands, feet, and nose can be affected. People who have all their fingers affected, rather than just one or two, probably have primary. Stress & cold are triggers. Stay away from cold or decongestant meds that have pseudoephedrine in them. My Dr. prescribed Adalat for it, but I haven't tried it yet(I'm the chicken, remember). Meds they usually prescribe are calcium channel blockers.
Now, after that research paper, it's time to rest. Take care, Ann
