In addition to the obvious pain during the acute phase of the bone healing process, the pain and swelling symptoms will be significantly relieved after two weeks. If the fracture site is still painful after two weeks, a relevant examination must be performed. Common causes include poor fixation, loose fixation or too much patient activity, which causes abrasion and displacement of the fracture end, resulting in painful symptoms. Pain after two weeks of healing is not a normal occurrence and requires appropriate examination to find the cause for treatment. The most common cause is the loosening of the fixation or too much activity of the patient, which causes local fracture instability and painful symptoms, so the symptoms must be examined in the hospital to take the appropriate treatment.
