If the fracture is painful, the fracture is likely to be re-injured, for example, if the fracture is struck by a hard object, causing secondary injury to the fracture, which can lead to pain. It may also be due to a lesion at the fracture site, such as local infection with osteomyelitis, which may also cause pain at the fracture site, as well as local redness and swelling, increased skin temperature, and in severe cases, sinus tracts. It is recommended that the patient observe the painful area for redness, swelling, and heat so that the condition can be determined. If there are painful symptoms at the fracture site, the patient is advised to go to the orthopedic department of the local hospital in time to improve the relevant examination. If the symptoms are mild, you can take anti-inflammatory and pain-relieving drugs such as ibuprofen or aminoglutethimide, but if the condition is serious, you must cooperate with the doctor to carry out the corresponding treatment to avoid delaying the condition.
