For about six months, i have been having these a cough that would not go away and white mucus ball fly out . the last month i have been wheezing too?

A cough: that does not go away with usual treatment should be evaluated. See your Doctor this week.

See MD for check up: Female no stated age, having cough that would not go away and white mucus ball fly out, plus wheezing in last month; likely due to Allergies to something (s) in the living/sleeping/ working environment. Smoking, Mold and infectious elements can also lead to Asthma which seems to be developing. 6 months is long enough, should see an MD
