Feeling a tickle in the chest and wanting to cough are mostly caused by respiratory infections, with inflammation of the trachea and bronchial tubes both stimulating local coughing symptoms, and may also be caused by infection in the chest cavity or pleurisy. The main purpose is to identify the location of the infection and the cause of the cough, and then make a correct diagnosis based on the test results. If you inhale irritating gases or smoke frequently, you need to quit smoking and pay attention to protection to avoid irritating gases to stimulate the respiratory tract, and pay attention to your diet and try not to eat spicy and irritating foods.
