Ibuprofen can be used for pain relief after a fracture if the pain is mild. If the pain is more serious, ibuprofen can not be used, the details are as follows: 1, for mild fracture, such as bone cracks and other incomplete fractures, patients with less local bleeding, less swelling, pain symptoms are usually not obvious, you can use ibuprofen to relieve pain, eliminate inflammation, and further promote the smooth healing of the fracture. 2, if a more serious fracture displacement, such as comminuted fracture, which belongs to the unstable fracture, the patient will have severe pain symptoms, accompanied by severe swelling. Ibuprofen is usually ineffective and stronger analgesic drugs, such as tramadol hydrochloride tablets and aminoglutethimide tablets, are needed to relieve pain.
