<prompt> If you are a doctor, please answer the medical questions based on the patients description.My 12 yr old daughter has had a rash on her back, stomach and neck for about 4 days. Does not itch or hurt. We have not changed lotion, soap or laundry detergent. Any thoughts? What symptoms should I look for that would indicate this should been seen by a doctor?  <response>: Hi...1. By what you quote it should be an urticaria or a simple skin allergy. You can use HY Chat Doctor. Most important thing to be remembered is that it has a propensity to recur called as second crop within 10-14 days. If this happens, you can start using the same medicine, but I suggest you get the kid evaluated with your pediatrician.2. Red flag signs or danger signs include - extremely painful joints blood in urine or stools rash localized to only legs sever tummy pain. Regards -
