My daughter has asthma. Her car, which she drives 5 days a week, has had a fault in the exhaust which I have only recently picked up, as I do not normally go in her car with her, that has allowed exhaust fumes into the car. She has had a cough for over 2 months which it now hurts down her arms when she coughs. She has just been to the doctors and has been told her chest is clear but has been given peneciln. I am worried about whether more needs to be done to help her
