The pleural cavity in healthy individuals is a potential space and is under negative pressure. Its main purpose is to allow the lungs to fully adhere to the chest wall, and the lubricating fluid present serves to prevent too much friction between the lungs and chest wall during deep inhalation, which could cause pain. For various reasons, such as a ruptured lung bulla or trauma to the chest wall, a certain amount of air can enter the pleural cavity, leading to pain in patients. Due to the presence of pleurisy, friction occurs between the lungs and chest wall—particularly between the lower chest wall and the lungs—causing intense pain during deep inhalations. If a large volume of air is present, it can prevent the lungs from fully expanding, potentially leading to symptoms of breathing difficulties or an obstructed exhalation.

Does pleurisy cause chest pain?

Pleurisy can cause anterior chest pain. It is a very common clinical disease, mostly caused by bacterial invasion of the pleura resulting in inflammatory lesions, with Mycobacterium tuberculosis being the most common pathogen. Due to inflammatory exudation, some patients may also experience varying degrees of pleural effusion. The clinical symptoms presented by patients mainly include fever, cough, shortness of breath, chest tightness, and chest pain. In severe cases, different levels of breathing difficulties and other clinical symptoms may occur. Therefore, it is very common for patients with pleurisy to experience anterior chest pain.

Is pleurisy serious in young people?

Pleurisy, when it occurs in young people, is also relatively common in clinical settings. It is primarily caused by an invasion of the pleura by Mycobacterium tuberculosis, resulting in an inflammatory lesion. The symptoms manifested by these patients mainly include coughing, shortness of breath, chest tightness, chest pain, and in severe cases, respiratory difficulties. Tuberculous pleurisy is mostly seen in adolescents and children. If young people are diagnosed with pleurisy and receive timely and accurate diagnosis, along with systematic and effective treatment with anti-tuberculosis drugs, their condition can generally be effectively controlled. However, it is important to note that although young people have better resistance, they must strictly adhere to the treatment duration for anti-tuberculosis medication, which usually spans six to nine months to completely cure pleurisy.

What is the cause of hemoptysis in pleurisy?

Pleurisy is generally more commonly seen in young adults and children clinically, and is most commonly caused by an infection of the pleura by Mycobacterium tuberculosis. Usually, patients with this type of pleurisy do not experience symptoms of coughing up blood. The typical symptoms caused by pleurisy primarily include chest pain, coughing, chest tightness, shortness of breath, and in severe cases with a lot of pleural effusion, it can cause the patient to experience breathing difficulties and sometimes chills. Therefore, the clinical symptoms presented by different patients can vary. When a patient with pleurisy has a severe cough, it can lead to the rupture of the capillaries in the bronchial walls, which can cause the patient to have varying degrees of blood in the sputum, or even coughing up blood.

Can pleurisy cause hemoptysis?

Pleurisy, this disease in clinical practice, does not cause symptomatic hemoptysis on its own. This is because pleurisy is mainly due to bacterial invasion into the pleural cavity causing inflammatory lesions. The pleural cavity is a sealed space, which, when inflamed, often causes symptoms such as fever, cough, chest tightness, shortness of breath, and breathing difficulties when there is a significant accumulation of fluid in the chest cavity. Generally, it does not cause hemoptysis. There is only one possibility, for example, intense irritative coughing in patients with pleurisy may rupture the capillaries in the bronchial walls. In this case, patients might experience varying degrees of coughing with blood, but this is not a direct clinical symptom caused by pleurisy itself.

The dangers of secondary recurrence of pleurisy

Pleurisy is very common in clinical settings, with most cases caused by the invasion of Mycobacterium tuberculosis into the pleural cavity, leading to inflammatory lesions. Patients generally experience pleurisy symptoms, and if their immune function is weak, some may relapse if not careful. Therefore, for patients recovering from pleurisy, it is essential to strengthen their immune system and pay attention to balancing work and rest, avoiding spicy and irritating foods, which can greatly reduce the possibility of pleurisy recurrence. If pleurisy recurs, the clinical symptoms may worsen compared to the initial infection or may present similarly to the initial symptoms. Generally, if pleurisy recurs, there might be severe complications due to adhesions in the pleural cavity, possibly leading to persistent chest pain symptoms.
