<human>: I have coughing problems with almost three months now.  It comes with yellow mucus, very irritating when meeting with lots of people.  I have shoulder pain for almost two weeks now.I took panadol (Back pain relief panadol) and coughing and pain just go and always come back.
<bot>: Thanks for your question on Chat Doctor. I can understand your situation and problem. In my opinion you should consult pulmonologist and get done1. Clinical examination of respiratory system. 2. Chest x-ray. 3. PUT (pulmonary function test). You are having chronic cough with expectorant. This is seen in lung infection and bronchitis. So get done chest x-ray to rule out lung infection. PFT is needed to rule out bronchitis. So better to first diagnose yourself and then start appropriate treatment. Don't worry, you will be alright.
