Lately i’ve been experiencing moments when my hands get cold and tingly then numb and weak and purple bluish color. veins from my both upper arms and shoulders leading to chest are bulging and visible. Vein in elbow is huge with reddening around and 2 visibly swollen or raised veins near wrist. the rest of my body is hot to the touch face is flushed ears are red and i feel too hot. lasts anywhere from 30 mins to few hours. happening more often and i’m getting concerned about my circulation.
