Why persistent itching without an obvious cause is a symptom you shouldn’t ignore

There isn’t a single person in this world who would say that they haven’t experienced what severe itching feels like. All of us have felt severe itching from time time,, and in most cases, it would have been caused by dry skin, allergies, insect bites or eczema . In such cases, the itching, though tiresome is temporary and harmless. But if the itching continues for weeks together without an identifiable cause or rash, it could be more than just a skin problem. Sometimes, the body gives us a signal of underlying medical condition through persistent itching.
