Hello. For the past year, I have been dealing with a nearly debilitating and overwhelming smell of smoke and burning metal. I have been getting bronchitis repetitively for the past couple of years. Recently while I was taking some classes, I was surrounded by several sick classmates, as well as the instructor (who was sick for nearly 3 weeks). Since then, I have been smelling burning metal and have trouble breathing. I also had a tooth extracted (with both laughing gas and IV sedation) about 3 weeks ago as well. I can t see my doctor for another week and don t know how I will get through each day with this horrible smell. I am loosing my ability to smell or taste things as well. Please help if you can.... Linda
