Around chest area and around the left side near chest area hurts when I cough. I frequently cough so hard like i want to throw up but  I did not.  Also back hurts when I cough. Breathing hard to feel better a little and the air makes me feel better. What is happening?
Thanks for your question on Chat Doctor. I can understand your concern. Chest pain on coughing with difficulty in breathing are seen in pleurisy (inflammation of pleura). Pneumonia and pleural effusion are common causes for pleurisy. So first get done chest x-ray. If chest x-ray is normal than no need to worry about pleurisy. Sometimes cardiac diseases can also present with similar symptoms. So get done ECG and 2d echo to rule out cardiac diseases. So consult doctor and discuss all these. First diagnose yourself and then start appropriate treatment. Hope I have solved your query. Wish you good health. Thanks.
