The bone in the middle of the chest hurts when pressed, that is, the sternal stalk location hurts when pressed. This situation is mainly due to two reasons: 1. It is possible that there are many attachment points for soft tissues such as muscles, tendons and ligaments in the sternal stalk position. If you keep a posture for too long or get cold, as well as lifting and carrying heavy objects, it may lead to strains, strain and the formation of sterile inflammatory lesions in these soft tissues, which will stimulate the peripheral nerves and cause pain. When pressing with the hand, it will produce direct stimulation to the lesion, so the painful symptom will appear. 2. It is possible that the sternal stalk location has suffered an external collision, causing the sternal stalk bone fracture or surrounding soft tissue damage, there will be obvious bruising, swelling and inflammatory edema, when pressing, it will lead to obvious stimulation and pain.
