Why do i have coughing spells that last for days and then produce lots of mucus that comes up like i am vomiting?

Infection: you may be having bronchitis or upper respiratory tract infection. i would want to know more about your sx like do you have any fever, sob, wheezing, chest pain, sinus pain or tenderness, post nasal drip . also what medications you are on and have you ever been diagnosed with any disease in the past schdule a consult for diagnosis of your problems thanks
