Left Chest Fork can sometimes heal itself in a week or so, but active management is recommended to avoid serious conditions. Left thoracic switchbacks are mainly due to insufficient preparation before strenuous exercise, resulting in the muscles entering a state of tension after strenuous exercise. And other organs can not move with the muscles to meet the provision of oxygen after exercise, leading to respiratory spasm and causing pain. Breathlessness can cause soft tissue injuries, showing localized pain that is obvious and can be alleviated with rest. If localized pressure pain, chest radiographs or chest CT examinations are found, there are no obvious positive results. It can recover on its own in about a week by resting and avoiding strenuous activities. If no relief is found, medicines to activate blood circulation and remove blood stasis, such as Hematopoeia and Blood Stasis Tang, can be taken, along with local physical therapy. Medications should be used under the guidance of a doctor and avoid self-medication.
