Clinical often have patients very panic to find the doctor said chest pain, after all, located in the chest organs that can not afford to be sick, can not afford to delay, so often electrocardiogram, chest X-ray, cardiac enzymes and so on to check a time. In fact, there is a very common clinical chest pain as the main manifestation of the disease – costochondritis, in particular, refers to the thoracic costal cartilage and rib junction of non-inflammatory swelling and pain, the onset of the site is common in the 2nd and/or 3rd rib cartilage and the sternal joint, occasionally in the 1st or 4th rib, rare in the other rib cartilage sternal joint or sternoclavicular joint. or sternoclavicular joint. In most cases, there is only one lesion, and in multiple cases, it is often unilateral. The cause of costochondritis is still uncertain, and is generally thought to be related to strain or trauma, and is most common in workers who carry heavy loads on the upper arm for long periods of time. The acute injury to the cartilage of the sternocostal joints caused by heavy lifting, sharp twisting or chest compression, or viral infection caused by chronic strain injury or upper respiratory tract infection, etc., causes myofibrillitis in the attachment part of the pectoralis major muscle, resulting in aseptic inflammatory reaction of edema and thickening of the cartilage of the sternocostal joint surface and the onset of the disease. Clinically, costochondritis occurs in 20-30 women, the ratio of male to female is 1:9. The onset of the disease can be acute or slow, acute people can be sudden onset, feel chest pain, throbbing pain or soreness; hidden attack is slow onset, after the onset of the rib cartilage at the enlarged lump, but the skin is not red, feel the chest pain or sharp pain, the most obvious pain in the outer edge of the sternum. The pain is relieved when resting or lying on the side, and is aggravated by deep breathing, coughing, lying down, lifting the chest and fatigue. In severe cases, the pain is aggravated by deep breathing, coughing or moving the upper limb on the affected side, and even the arm cannot be lifted. After the pain disappears, the mass may remain for a long time, and the disease often resolves on its own within a few months, but in some cases it may continue for several years. x-ray pictures are normal, or calcification of the costal cartilage can be seen. Tissue taken from the diseased area shows edema of the perichondrium and surrounding soft tissues. In women, costochondritis is often confused with breast pain because the pain often radiates to the breast, so most people present with breast pain. The main points of differentiation are: if it is a disease of the breast itself, you can often feel a lump or stripes in the breast, or localized redness of the skin of the breast, etc.; while costochondritis is often exacerbated by coughing, deep breaths, lifting the arm, sideways, etc., the pain in the breast is not affected by these factors. In terms of treatment, this disease is a self-limiting disease, so the treatment is mostly symptomatic, can give local hot compresses or microwave, physiotherapy; oral non-steroidal analgesic drugs for symptomatic relief, restoration of the quality of life has a good therapeutic effect; can also be given to the appropriate antiviral drugs, such as: virus spirit 0.1g, 3 times a day; for the more serious symptoms of the local injection of prednisolone acetate closure therapy.
