Bronchial cysts can compress the bronchial tubes causing symptoms such as coughing, wheezing, and difficulty breathing. When the bronchial cyst is small, there are usually no obvious symptoms. If it is large and compresses the trachea bronchus, symptoms such as coughing, wheezing, and dyspnea may occur to varying degrees. When the cyst is larger and compresses the surrounding tissues, chest tightness, chest pain, difficulty in swallowing and other manifestations may also occur. If you have the above symptoms, you must go to the hospital in time for examination and treatment under the guidance of the doctor, and do not take it lightly, so as not to cause adverse consequences.
