So I have chronic urticaria and my C U index was 38. Can this make you more sensitive to the sun?

In brief: Maybe; see allergist

People with chronic urticaria get hives randomly and spontaneously, usually NOT in response to environmental exposures.
But sometimes things like warming the skin (e.g., sun exposure) can bring out hives; you just have to try it an see. High-dose antihistamines are often helpful at preventing hives, but there is an injectable medication that works well, especially with a positive CU index.
