Hi I am a 58y/o black female with diagnoses of discoid lupus, arthritis, asthma, hypothyroidsm, hypertension, gerd.. I have been coughing through the years even while at work. Now I am coughing all day with clear phlem at frequent intervals. Very hard to stop coughing. I have a very tangy taste to acidic after coughing up the phlem. Food seems to stimulate the cough. Wow I know a lot of information. My doctors just treat the asthma, but I think there is something there that they have not figured out yet. Meds are atenolol, plaquinil, Tylenol , tramadol, synthroid, previcid.
