What are the symptoms of diaphragmitis?

Diaphragmitis is an inflammation of the pleura in the chest cavity. The pleura has two layers. One layer covers the surface of the lungs, called the visceral layer; the other layer is attached to the chest wall and is called the parietal layer. The cavity between the two layers of membrane is called the pleural cavity. If this layer of membrane is inflamed, it must be treated early, otherwise it will become more serious if left untreated, and may infect the surrounding healthy tissues and organs, and then cause systemic infection through blood circulation, endangering life. The following editor will give a detailed introduction to the situation of diaphragmitis.

Overview

The pleura is a layer of serous membrane that covers the surface of the lungs and the inner side of the thorax, which are called the visceral and parietal pleura respectively. The two layers of pleura form a gap called the pleural cavity. Under normal circumstances, the pleural cavity contains only a small amount of serous fluid, which acts as a lubricant, reduces friction between the two layers of pleura, and prevents adhesion. Pleurisy is an inflammation of the pleura, which can be caused by a variety of diseases such as infection (bacteria, viruses, fungi, ameba, lung fluke, etc.), tumors, allergies, chemicals and trauma. Among pleurisy caused by bacterial infection, tuberculous pleurisy is the most common type of pleurisy. This section focuses on tuberculous pleurisy.

Clinical manifestations

Dry pleurisy: Because the visceral and parietal pleura are close to each other and rub against each other, it manifests as a knife-like chest pain on the affected side. The pain is most obvious when taking a deep breath or coughing. The symptoms of tuberculosis poisoning are mild. During physical examination, respiratory movement on the affected side is limited, and pleural friction sounds can be heard during auscultation.
