Swelling and itching of hands warrant an urgent visit to a dermatologist, an Urgent Care facility, one's physician, or a hospital Emergency Department. The task is to determine the underlying cause of these symptoms. Causes include contact substances inciting an allergic skin response, a systemic allergy to some ingested substance, a food allergy, a systemic disease, or some other cause.
