There may be several reasons why the rib fracture is still painful after more than 50 days: 1. Poor recovery of the fracture end, rib fracture is preferred to conservative treatment, and the time of bed rest is decided according to the number and location of the rib fracture fracture, the bone scab will start to grow 4 weeks after the fracture, which means the fracture starts to heal. If the rib fracture is still painful for more than 50 days, the rib fracture is not a multiple fracture, it may be related to slow or abnormal growth of the bone scab, poor growth of the bone scab at the fracture end leads to less bone trabeculae passing through, thus leading to poor recovery of the fracture site and still painful. 2. Multiple rib fractures, if it is a multiple rib fracture, the number of rib fractures is high and still painful at the fracture site is a normal symptom, because multiple rib The fracture requires bed rest for about 2 months before you can get out of bed. 50+ days of activity may be when the multiple fracture has not fully healed, which can lead to a tendency to displace the fracture end to produce pain.
