G.H.
My mom has been having these same symptoms for 2 years, the doctors have ruled out just about everything...they do know she has some form of vasculitis, but it is a secondary disease and they have no clue what could be causing it. She has recently gotten critical, and the doctors are still baffled. She has lost the use of her hands and legs below her knees, and the affected areas have turned purple and black from lack of circulation. She is in an enormous amount of pain. I hope yours does not get this bad. Good luck.
