Pectoralis major pain

Introduction Pectoralis major muscle pain is generally aseptic inflammation of the pectoralis major muscle attachment ("sterile inflammation" is a part of the body's body disorders and stubborn pain without bacterial infection, pathological examination and tissue section can not find any microbial infestation The signs are sterility from the pathological changes, and there is no inflammation of the pathogenic bacteria, so the antibiotic treatment is ineffective. "Aseptic inflammation" is the second largest type of inflammation that causes inflammation of the body, because there is no bacterial infection, no It will produce high heat toxicity and suppuration and severe redness in the human body like "bacterial inflammation".

Cause

Tension of the pectoralis major, strain, cervical lesions, chest inflammation, soft tissue damage, etc.

an examination

Muscle tone test

If there is a sterile inflammatory lesion at the attachment of the pectoralis major, there will be localized pain and conduction down to cause pectoral myalgia or breast pain. Because sedentary does not exercise, but it may also be due to poor sitting posture, cervical vertebrae stretching, causing muscle tension in the posterior and bilateral sides of the neck, such as sternocleidomastoid muscle and trapezius muscle, thus affecting the pectoralis major muscle is also nervous, resulting in chest Great muscle pain.

A unilateral case with extremely severe soft tissue damage outside the spinal canal will also lead to pectoralis major myas or breast pain, or a snorkeling sensation along the abdominal wall until the inner thigh, and abdominal wall cords will appear when jumping; Lateral cases will also lead to chest pain, chest tightness, poor breathing and other signs of the chest. Cervical spinal pain, cervical spine, ipsilateral scapula, and pectoralis major areas often have tenderness.

Inspection method: The examiner uses the tip of the thumb to slide along the anterior portion of the 1/2 segment of the clavicle and the anterior portion of the 1/3 of the clavicle, and the two tender points can be found separately.

Differential diagnosis

Differential diagnosis of pectoralis major myalgia:

1, chest pain: chest pain is a common symptom in the emergency department, usually caused by chest disease, the severity of chest pain does not necessarily have a definite relationship with the cause of chest pain, such as chest herpes zoster can produce severe chest pain, and acute myocardial infarction Chest pain is sometimes not very serious.

2, chest wall pain: chest wall pain (chestwallpain) also known as musculoskeletal pain (musculoskeletalpain).

3, breast pain: the symptoms of breast hyperplasia disease is mainly characterized by periodic pain in the breast. At first, it was a painful pain, and the tenderness was obvious in the upper and middle upper parts of the breast. The pain was exacerbated before menstruation every month, and the pain decreased or disappeared after menstruation. In severe cases, persistent pain was observed before and after menstruation. Sometimes the pain radiates to the ankle, shoulders, upper limbs, and the like. Patients often report a mass in the breast, but only the thickened mammary glands are touched during clinical examination. There are very few puberty simple breast lobular hyperplasia that can heal itself in about 2 years, and most patients need treatment. Don't endure it.

4, the intercostal space may have tenderness: the intercostal space may have tenderness is the clinical manifestation of intercostal neuralgia. Physical examination of patients with intercostal neuralgia found that there was significant tenderness in the paraspinal and intercostal space of the thoracic spine; typical patients with intercostal intercostal neuralgia had a positive neck test; the distribution of affected nerves often showed neurological impairment such as hyperesthesia or hypoesthesia. .

5, dry hypochondriac pain: Chinese medicine said that the dry hypochondriac pain is due to pulmonary sputum and other lesions invading the pleura, burning sputum, qi and blood stasis, collaterals. It is a painful disease mainly characterized by chest pain, dry cough, and pleural friction sound.

6, the second costal cartilage pain: costal cartilage inflammation is slow. Its prominent clinical manifestations are affected gastric cartilage bulging, swelling, obvious spontaneous pain and tenderness, local redness and heat changes. In most cases, only a single costal cartilage is invaded, and there are also more than 2 cases or multiple bilateral costal cartilage in individual cases. The most common lesion-prone site is the left second costal cartilage, followed by the right second costal cartilage and the third, fourth, first costal cartilage.

7, side rib pain: experts do not know what causes rib pain, it is generally considered to be related to daily life, such as exercise beyond the ability, improper sucking, dehydration or exercise immediately after meals.
