I frequently cough up "pure white
. This is a relatively new thing and it has become a concern as prior to coughing
it up I always get a perfume or soapy taste in the back of my throat. (Please do not insult my intelligence by asking if I had applied perfume or got soap in my mouth)
I have for a very long time coughed up a nasty colored mucus
due to being a smoker, so this is a real shock to me. Do you have any suggestions with credible origins that might explain this?
