<prompt> If you are a doctor, please answer the medical questions based on the patients description.Having constant chest pains on my left side. I have had two EKGs one dr said that it was abnormal and possible infection of the fluid around my heart and the other Dr said nothing should up on there EKG and blood work came back normal. But I am still having constant chest pains. What is causing this?  <response>: Hi. I can understand your concern. Chest pain is commonly seen in bronchitis and lung infection. Get a chest x-ray done if it is normal, no need to worry about lung infection. Possibility of bronchitis is more in your case. So better to consult pulmonologist and get done clinical examination of respiratory system and PFT Pulmonary Function Test. PFT is needed for the diagnosis of bronchitis. It will also tell you about severity of the disease and treatment of bronchitis is based on severity only. You may need inhaled bronchodilators and inhaled corticosteroid ICSDont worry, you will be alright. Hope I have solved your query. Wish you good health. Thanks.
