For years i have got intense itching in various parts of my body including feet, hands, legs and around the ball sac. its never in all places at once and even when i scratch it doesnt go away. indeed i usually draw blood before i stop scratching and these

Unsure of cause: Generalized itching can be from any number of causes including severe liver or kidney problems. However, it is much more commonly from dry/irritated skin. Excessive scratching induces more skin irritation and often makes it worse. If no other symptoms, try aggressive skin moisturization for a week (multiple times a day and always after bathing when skin is moist) with non-alcohol based lotion.
