Hello, i have had a bad cough for the last 2 weeks now and itss driving me crazy. i beleive its called a rattling cough. at first i thought it could be due to the time of year, i have allergies to the pollen tht floats outside, but its lasted too long i dont think thats what it is. my throat feels scratchy and i tend to find myself having to clear my throat every few minutes. could this be a regular flu or cold, or is it something more serious?
