All I can report about is my own experience with my son. His facial coloring is that of a chemo patient or drug addict. He is white, pasty, has fainted several times, has blue lips on many occasions, can't gain weight, has vestibular problems, sinus arithmia (irregular heartbeat), always cold, lethargic, virchow robbins spaces (like in ms), difficult birth (salmon patches on back of head), hiccuped multiple times a day - everyday of his life for the first 2.5 yrs, only has pink on the tip of his nose...My family has a history of vascular issues. My mom has had both neck arteries unclogged. So have most of my uncles.
Is there any proof that this is not a vascular problem?
