DD (3) came out last week in fast spreading rash that doctor diagnosed as uticaria probably as a reaction to a virus she had had. No known allergies. She has been having piriton since which has some effect. Sometimes it looks really bad others not so much. Question is she is due to start swimming lessons tomorrow, do we take her? doctor says it's not infectious so no problem. Just wondered if anyone else had experience of this? Don't want to make it worse but also am concerned what the other parents might think. Any advice would be gratefully received!
