Can you tell whats up with me its herd to breath as well. [/INST] Thanks for your question on Chat Doctor. I can understand your situation and problem. By your history and description, possibility of pleuritic chest pain is more. And it is seen commonly with lung infection and bronchitis. You are also having cough and difficulty on breathing so possibility of bronchitis and lung infection is high. You also had flu infection. And this can also cause bronchitis and lung infection. So better to consult pulmonologist and get done clinical examination of respiratory system, chest x-ray and PFT (Pulmonary Function Test). Chest x-ray is needed to rule out lung infection. PFT is needed for the diagnosis of bronchitis. You may need inhaled bronchodilators, inhaled corticosteroid (ICS) and antibiotics. So better to first diagnose yourself and then start appropriate treatment. Hope I have solved your query. Wish you good health. Thanks. </s>
