Itching can sometimes be psychosomatic in nature, caused by severe states of anxiety or stress.
Psychosomatic itching is localized to a specific location on the body, not resulting from internal physical factors or factors external to the affected individual.
It occurs preferably in the evening and at particular times of tension.
What makes it appear ishistamine, a substance inherent in the human body that is an irritant and causes itching, produced to counteract possible allergens.
Relief from this disorder may come from taking calming herbal teas to decrease the state of tension underlying the problem.
