Im 32 have had athsma my whole life but been under control for more than 10 years, Im always prone to coughing throughout the year I cough up pale yellow Spetum, but recently after I cough It tastes dusty?I do work in dusty conditions sometimes on mine sites.
Dust causes increased secretion of mucous. Mucous try to trap dust to prevent it getting in lungs tissue That's why cough taste dust
