Every time I visit a friend I notice heavy smell of moth balls and within 10-20 minutes I feel lightheaded and restriction in my breathing. I later learned she uses them in high quantities, and sprinkles them all over her house. Anytime I have visited and left her house I feel dizzy, heavy wheezing, gasping hard for air, and then at night when I am lying on my back I hear/feel crackling (like bubbles popping or rice crispy's popping) in my throat. Last year the symptoms worsened and had a fever of 103 for nearly 4 weeks with excessive coughing, wheezing, weakness, dizziness, and pneumonia like symptoms. Is this an effect from the moth balls?
