Yes: Anxiety and stress are possible causes of itching in the absence of dry skin. See your doctor to rule out other potential causes such as liver problems. Use stress management techniques and consider cognitive-behavioral techniques to control anxiety. Often, professional treatment by a psychologist or psychiatrist can help if your primary care doctor is not able to provide relief.

Agree w responses: you have received so far. Just wanted to add than when hives are related to anxiety - placement of acupuncture needles (such as 5 Gates) can lead to immediate resolution of symptoms. Concur with earlier statement that causes other than anxiety should also be ruled out.
