hello, my 26 year old daughter has some red welts on her arms, legs, stomach, back and each day there seem to get a little more. They don t itch or are raised. They are just red welts spreading. She is white, and she hasn t changed her eating habits, detergent. Says they aren t bites. No one in her apt. has anything on them. Her fiance doesn t have anything on him either. She doesn t have pets. She thinks it could be stress related. She s a little anxious about it. What do you think? my email is YYYY@YYYY
