This is all very interesting to me, too, Rina. I rarely talk about how mine came on because it is so wierd that I thought people would think I am a nut. I was having trouble with migraines. I had a terrible one one night and had to go to the Emergency Room. While I was laying on the bed there, all of a sudden I noticed that my feet were in extreme pain also, and that my toes were numb. I thought that my circulation must have been cut off and when I looked at my feet I expected them to be blue or black! But they looked pink and warm. The numbness and pain has never gone away, just gotten worse and progressed upwards some. I have always felt that the excrutiating migraine pain had made something "snap" in my body or brain, and now I can't get the pain turned off. Just a crazy theory.
