I have shoulder and chest pain after bending over for a long time.

Everyone's working situation is different. Some people sit for a long time while others stand while others need to bend over frequently. The different nature of work also causes people to have different occupational diseases. Many people experience shoulder and chest pain after bending over for a long time. You should pay special attention to chest pain to see if you have pleural or angina disease.

What are the typical symptoms of pleural diseases?

Symptoms 1. Age of onset of pleural diseases: Chest pain in young and middle-aged people is often caused by tuberculous pleurisy, spontaneous pneumothorax, myocarditis, cardiomyopathy, and rheumatic valvular heart disease. People over 40 years old should pay attention to angina pectoris, myocardial infarction, and bronchial lung cancer.

Symptom 2. Duration of chest pain: Pain caused by smooth muscle spasm or vascular stenosis and ischemia is paroxysmal, while pain caused by inflammation, tumor, embolism or infarction is continuous. For example, angina attacks are short-lived (lasting 1-5 minutes), while the pain of myocardial infarction lasts for a long time (several hours or longer) and is not easy to relieve.

Symptom 3. Factors that affect pain are mainly the triggers of pain, factors that aggravate and relieve pleural diseases. For example, angina attacks can be induced by exertion or mental stress, and can be relieved within 1 to 2 minutes after rest or taking nitroglycerin or isosorbide dinitrate. However, the above medicines are ineffective for pain caused by myocardial infarction. Esophageal diseases often occur or worsen during eating, and can be alleviated or eliminated by taking antacids and prokinetic drugs. What are the typical symptoms of pleural diseases? The chest pain of pleurisy and pericarditis can be aggravated by coughing or breathing hard.

Symptom 4. Nature of chest pain: The degree of chest pain can be severe, mild or dull. The nature of chest pain can vary. For example, herpes zoster causes severe pain like a knife cutting or burning; esophagitis often causes burning pain. What are the typical symptoms of pleural diseases? Intercostal neuralgia is paroxysmal burning or stabbing pain; angina pectoris is a squeezing pain with a feeling of heavy pressure and suffocation, and the pain of myocardial infarction is more severe and there is a sense of fear and impending death; pneumothorax has a tearing pain in the early stage of the disease; pleurisy often presents dull pain and stabbing pain; dissecting aneurysm often presents sudden tearing pain or piercing pain in the chest and back; pulmonary infarction may also cause sudden severe chest pain or colic, often accompanied by difficulty breathing and cyanosis.

Symptom 5. Location of chest pain Most diseases cause chest pain in a certain location. For example, chest pain caused by chest wall disease is often fixed at the site of pleural disease lesions, and there is local tenderness leading to pleural disease.

① Inflammatory lesions of the chest wall skin, which may be red, swollen, hot and painful locally; Herpes zoster refers to chest pain, with clusters of blisters distributed along one side of the intercostal nerve accompanied by severe pain, and the blisters do not exceed the middle line of the body surface;

② Chest pain caused by costochondritis. Pleural diseases often cause single or multiple bulges at the first and second costal cartilages, with local tenderness but no redness or swelling. The pain of angina pectoris and myocardial infarction is mostly behind the sternum and in the precordial area or under the xiphoid process, and can radiate to the left shoulder and inner side of the left arm, or even to the ring finger and little finger, or to the left neck or cheek, which can be mistaken for toothache.

③The pain caused by dissecting aneurysm is mostly located in the chest and back, radiating downward to the lower abdomen, waist, groin and lower limbs on both sides; the pain caused by pleural disease is mostly in the side of the chest; the chest pain caused by esophageal and mediastinal lesions is mostly behind the sternum; the chest pain caused by hepatobiliary disease and subphrenic abscess is mostly in the right lower chest, and when invading the center of the diaphragm, the pain radiates to the right shoulder; the pain caused by apical lung cancer (superior pulmonary sulcus cancer, Pancoast cancer) is mostly caused by shoulders and armpits, radiating to the inner side of the upper limbs.
