Bronchitis can be recovered by itself. Bronchitis is usually caused by a sudden strong contraction of the intercostal soft tissue when moving something hard or coughing hard, which leads to strain of the intercostal muscles or soft tissue and causes chest pain. When the local soft tissues or ligaments and muscles recover on their own, the local pain will be slowly relieved, but the time to relieve itself may be relatively long, must be about 2-3 weeks, because people need to breathe 24 hours a day, every breath is, the chest must rise and fall, however, the injured soft tissues of the chest will also have activities, so the injured muscles and ligaments have not been well The injured muscles and ligaments are not well recovered, and the relative healing time will be longer, but as time goes backward, the symptoms will naturally disappear after the ligaments heal.
