I have occasional breaking out, itching, stinging on my torso. It may appear on my back, shoulders, sides near breasts, or stomach area. When I scratch to relieve the itching, it turns to welts. Sometimes I think it is related to nerves, namely anxiety. I am visiting in a home where there is a dog, doberman mix. It is sweet dog, but I do not care at all for dogs---the mess they make, the odor, being allowed around the table during meals. It makes me very upset and nervous.
