I do no thave a cold or any cold symptoms, but since last night out of the blue i started this dry, hacking cough. Today, I coughed so hard it felt like someone punched me in my chest and hurt pretty badly. Now, it hurts very badly even with the smallest cough and I can feel pressure on my chest constantly. What could this be?
Thanks for your question on Chat Doctor. I can understand your concern. Sudden onset coughing with chest pain and pressure are seen commonly with lung infection or bronchitis. So better to consult pulmonologist and get done clinical examination of respiratory system, chest x-ray and PFT (Pulmonary Function Test). If all these are normal then no need to worry much. Take levocetrizine and paracetamol twice daily. Do warm water gargles 5-6 times a day.  Chat Doctor.  You will mostly improve with all these in 2-3 days. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
