I have been having strange symptoms recently and went to my doctor with them. A couple years back I started to notice that when I stand for awhile, get up from a supine position , or are exposed to heat my feet turn deep purple and red, and they feel as if they are engorged with blood. I can see a definite start to it about mid-thigh. The opposite effect happens when I lay down, they turn white and cold and numb. I have a history of anemia, endometriosis, high blood pressure. I am twenty three years old and I haven't felt well since I was eighteen or so. My mother has these same things going on and more including degenerate joint disease. I am worried about lupus because my doctor recently ran some tests for lupus and other immunodeficiencies. Did any one else's start like this? Or am I worrying about nothing?
