This began last winter and stopped as the weather warmed. Now again, the mornings are cooler, and I m breaking out in hives in the mornings. I bathe in the mornings but haven t changed bath soap or laundry detergent in years. Neither have I changed the things that I eat for breakfast. I take Zyrtec daily for seasonal allergies but this doesn t seem to stop it. The hives are always on my bottom, hips, stomach and upper legs as well as on my upper arms. Also, though they always occur in the morning, the time of the morning may vary by several hours. Last year this went on for weeks at a time with few breaks. Thanks.
