No cough but chest X-ray still shows inflammation

Whenever the seasons change, many people are prone to colds and other related symptoms due to the sudden attack of cold air. Colds are often accompanied by coughing, runny nose and other discomforts. This is also the body's way of warning us that we may face serious inflammatory interference. But some people go to the hospital for a checkup and find that they don't have a cough, but the chest X-ray still shows inflammation. What's going on?

1. If there was inflammation, the symptoms would disappear after regular treatment, but the chest X-ray findings would not be synchronized with the improvement of symptoms; that is, the imaging lesions would not be completely absorbed until several weeks or even months after the symptoms disappeared. Suggestions: If the above situation occurs, it is recommended to observe it first and rule out the possibility of illegal shadowing.

2. The patient had recurring fever for a week, and intravenous drip had no effect. There was no cough or runny nose, and blood tests were normal, while chest X-rays showed some mild inflammation. Consider that it may be caused by pneumonia! It may be caused by a viral infection. Hello, from your description, you have symptoms of repeated fever and cough, and a chest X-ray examination diagnosed you with lung inflammation. It is also recommended that you check for mycoplasma.

3. Bronchitis refers to a chronic nonspecific inflammation of the trachea, bronchial mucosa and surrounding tissues. The main cause of bronchitis is repeated infection by viruses and bacteria, which results in chronic nonspecific inflammation of the bronchi. When the temperature drops, the small blood vessels in the respiratory tract spasm and ischemia, and the defense function decreases, which are conducive to the onset of disease; chronic stimulation such as smoke, dust, and polluted atmosphere can also cause the disease; smoking causes bronchospasm, mucosal mutations, reduced ciliary movement, and increased mucus secretion, which is conducive to infection; allergic factors also have a certain relationship.

4. Acute bronchitis often presents with symptoms of upper respiratory tract infection in the early stages, and patients usually have clinical manifestations such as nasal congestion, clear runny nose, sore throat and hoarseness. The systemic symptoms are relatively mild, but may include low fever, chills, general fatigue, itchy throat, irritating cough and pain behind the sternum. In the early stage, the amount of sputum is not much, but it is not easy to cough up. After 2 to 3 days, the sputum may change from mucous to mucopurulent. Coughing may be aggravated or induced by the patient catching a cold or inhaling cold air or irritating gases. Patients often have a more severe cough in the morning or at night. The cough may also be paroxysmal or sometimes persistent. Severe coughing is often accompanied by nausea, vomiting, and chest and abdominal muscle pain. If accompanied by bronchospasm, there may be wheezing and shortness of breath. Generally speaking, the course of acute bronchitis is self-limited to a certain extent, and systemic symptoms can subside within 4 to 5 days, but the cough can sometimes last for several weeks.
