Detailed answer

Hives or urticaria is a skin condition characterized by raised, itchy welts or bumps on the skin. It is caused by an allergic reaction or other triggers like stress or medications. Hyperpigmentation, on the other hand, refers to the darkening of certain areas of the skin due to an increase in melanin production. It can occur due to various factors like sun exposure, hormonal changes, or skin injury. While both hives and hyperpigmentation can be skin-related issues, they are not directly related. Hives usually do not cause any long-term changes in skin pigmentation. If you are experiencing hyperpigmentation, it is advisable to consult a dermatologist to determine the underlying cause and appropriate treatment options.
