### Human:\ni'm 45 and have only developed excema now. why would that be? . i've only had the excema for the last couple of months. i haven't changed laundry detergent have lived in the same place for 3 years and wear more or less the same types of clothing that i always have. i am lactose intolerant but have been this way for the last 7 years. excema does not run in my family. any cause the sudden onset?\n\n### Assistant: hi your find that eczema can come in lots of ways stress could do it see it can come from within and not from what we touch have you seen a dermatologist yet could be good place to start from even if its just for some ideas. but your looking good for 45 nice smile. hope this helps you. good luck
