Itching: Generalized itching without a rash can be due to dry skin, diabetes, liver or kidney disease, thyroid disorders or even anxiety. Your physician can evaluate you and order any appropriate tests for both the itching and intestinal problems(possible lactose or gluten intolerance,irritable bowel syndrome). Taking benadryl (diphenhydramine) at bedtime relieves itching.
