I Have COPD From Exposure To Pesticides Several Years Ago

i have COPD from exposure to pesticides several years ago i was doing fine then last week at pulmonary
rehab i was exposed to cigaretter smoke smell. my throat and lungs have been burning since and am very sensitive to most smells. dr gave me antibiotic and prednisone to calm things down. Have been on them for 3 days. still cant talk and burning still intense. I am on flovent now for a month too. feel like i am having an allergic reaction to something
