According to the symptoms that God explains, there may be a terminal artery disease, which occurs when the arteries of the legs are blocked or narrowed, and the blood circulation is not smooth, and the cold feeling can be caused by the loss of blood flow in the limbs, as well as the loss of blood flow in the lungs.
Doctor, I've been having symptoms that my leg's circulation doesn't go well and I'm often cold, and I've been vomiting blood lately.
