My 35 year old daughter has a chronic cough, sometimes it s heavier than others, she says it s the air, she is loosing her hair (slowly), she gets frequent ear aches and sore throat, she is constantly tired. She says they never see anything on her lungs when she gets her lungs checked at the free clinic, she is not sexually active. and her teeth are shifting, she does not smoke, or do any kind of drugs, she works with children.
