Pain In Left Area Of Head, Mid Lower Back, Tingling Sensation, Chest Pain, Sunken Eyes, Sore Leg

I have quite frequent sharp pains in the left area of head that turns into a tingling sensation. Chest pains that only last a few minutes but are bad when it happens. The veins across my chest and arms, going into my neck up my face are getting more visible. Eyes are severely sunken in and black... Pain in my mid lower back.. Sharp pains that dont last long.. And finally my left leg is very sore, the veins behind my knee are severely swollen and sore. They are itchy, burning, lumpy, spreading and it shoots throbbing pain through my leg..
