Hi Ann S.,
I talked to my Mother and she said that her's was triggered by Verapamil (spelled wrong maybe?) which is a high blood pressure medicine that she had to stop taking because of the Raynauds Phenomenon. Unfortunately she kept the disease. She did some research and discovered that Alpha, Beta and Calcium blockers can cause it. The doctor told her to move out of Minnesota (yes,we live here too, oddly enough! *laugh*) and avoid stress.
Thanks so much for the link, she's still researching it and trying to find ways to aleviate it also. If we find anything that works for us, we'll post back.
Take Care

Lori
