Chest pain

Chest pain is a common clinical symptoms, many reasons, and the location and severity of chest pain, and not necessarily the site and severity of lesions consistent. Trauma, inflammation, cancer and certain physical and chemical factors to stimulate tissue damage caused by intercostal nerve, phrenic nerve, spinal nerve roots and the vagus nerve in the public distribution of the esophagus, bronchus, lung, pleura, heart and aorta nerve did not shoot, can cause chest pain. When discrimination can be analyzed belongs to which category, then identification of the various reasons for this category.
1, chest wall lesions
Chest pain, chest wall caused by the change of various types of chest pain is the most common form, such as local skin of the chest wall trauma, bacterial infections, viral infections, cancer and other causes of muscle, bone and nerve disease. Common acute dermatitis, inflammation of the subcutaneous cellular group, herpes zoster, painful obesity, polymyositis and dermatomyositis, epidemic myalgia, neck pain, rib cartilage inflammation, bone tumors, intercostal neuritis, nerve root pain . Wherein the common characteristics: 1. Pain is fixed to the lesion site, and there are obvious local tenderness. 2. Take a deep breath, coughing, lifter arm, bending and other movements thorax pain intensified activity.
2, lung and pleural disease
Lung and visceral pleura is not sensitive to pain perception, pneumonia, tuberculosis, lung abscess, pulmonary infarction, while chest pain due to the lesions involving the parietal. Lung cancer invading the bronchial wall and parietal pleura can produce chest pain. Spontaneous Because adhesions tearing produce sudden pain. Dry pleurisy friction due to inflammation spread to the visceral and parietal pleura caused chest pain occur. Identify a large number of pleural chest pain and tension pneumothorax may occur due to the parietal pleura pressure. Their common characteristics are: 1. more associated with cough or sputum. 2. often due to coughing, deep breathing and chest pain increased, other activities do not cause chest pain, 3 chest no local tenderness. Often accompanied by symptoms of primary disease symptoms, X-ray examination can be found lesions.
3, cardiovascular diseases
Common cause of angina, myocardial infarction and pericarditis. Angina pectoris, myocardial infarction, aortic valve disease and cardiomyopathy lead chest pain caused due to cardiac ischemia. Pericarditis is due to lesions involving the fifth rib below the level of the parietal pericardium and adjacent pleura and pain, their common features are: 1. chest pain or heart more in the front region, a few in the xiphoid, the radiation to the left shoulder, 2. The pain often due to physical activity-induced increase, improved after the break.
4, mediastinal and esophageal lesions
Less common, a common cause of acute inflammation longitudinal things, mediastinal tumors, mediastinal emphysema, acute esophagitis, esophageal cancer and so on. Mediastinal disease is caused mediastinal tissue pressure, nerve or bone involvement and other factors cause chest pain. Esophageal diseases mainly due to inflammation or chemical irritants caused by acting on the esophageal mucosa. Common features: chest pain in the chest, was ongoing pain or pain in the drill, often radiating to other parts. Swallowing pain intensified, accompanied by difficulty swallowing.
5, mold diaphragm disease
Can cause or be caused by celiac disease crying dirty diaphragm itself, common is diaphragmatic pleurisy, subphrenic abscess, diaphragmatic hernia, hepatitis, liver abscess, liver cancer. Chest pain caused by diaphragmatic disease is due to phrenic nerve stimulation. Its characteristics are: general pain located in the lower part of the chest and sternum. When the central diaphragm irritation, pain may radiate to the shoulder and neck.

Measures:
1. suspected angina pectoris, immediately oxygen, rest, sublingual nitroglycerin.
2. chest pain caused by pleurisy or pleural disease, can be used in a wide cummerbund at a fixed chest wall pain, relieve thoracic breathing when the degree of motion.
3. to the hospital ECG and X-ray examination confirmed immediately, treatment for the cause.
4. appropriate to take painkillers.
