Thanks for your question on Chat Doctor. I can understand your situation and problem. Since your PFT (Pulmonary Function Test) is normal, no need to worry about asthma. Possibility of lung Infection or pleural effusion is more in your case. Constant coughing is seen in both of them. Pleural effusion can cause diaphragm irritation. Diaphragm and shoulder joint share common nerve supply. So diaphragm irritation can cause referred pain in shoulder. So possibility of either pleural effusion or lower lobe pneumonia is more. So wait for your x-ray report. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
