Hello, Chest pain is and the sensation of air filling the chest is very common with a viral infection but if you are having common cold for more than a week now, or you are any worse or you have any fever, fatigue, shortness of breath or bring up phlegm with cough or have chronic conditions such as diabetes, heart and lung problems, etc, it is best to have a check with your doctor. In this case, the doctor will check your lungs and if lung infection is suspected you will need oral antibiotics. I hope this answers your query and is helpful to you. Let me know if I may assist you further. Regards, Dr. Antoneta Zotaj, General and Family Physician
