Should i be worried if it hurts my chest when i take a deep breath or cough? i haven't been feeling to good and my cough is dry.

Respiratory issue: Chest pain with deep breathing can be seen with pleurisy, inflammation of the lining of the lung usually seen with infections. Coughing, dry or wet, can be a symptoms of a respiratory infection (lung or sinus). Other possibilities also exist. An evaluation including chest x-ray and lung function tests are likely to lead to the diagnosis so a treatment plan can be offered.
