It is not normal for a rib fracture to be painful after two and a half months. Usually, when a rib fracture is two months old, the bone scab has started to grow and the patient does not feel pain anymore. When the pain is still felt, it may be because the bone scab has not grown and the fracture site has not healed, the fracture line is still clear and the patient still has pain when breathing. Patients can go to the hospital for an examination to find out what is causing the slow recovery of the fracture end. If one’s own recovery ability is poor, poor physical fitness, older or scarred, the fracture site will still recover more slowly and take longer to recover. Another factor is that the tissue around the fracture site has a sterile inflammation caused by the fracture, you can take anti-inflammatory and pain-relieving drugs, such as ibuprofen or diclofenac sodium, which are more effective.
