Pain can occur two years after a rib fracture, probably because the fracture was more significantly misaligned at the time and was not treated properly, resulting in long-term compression of the intercostal nerve at the fracture end, which leads to pain. Usually, in addition to pain at the rib fracture site, this pain is also associated with pulling or discharge-like pain of the intercostal nerve, which can usually be treated symptomatically with oral application of nonsteroidal anti-inflammatory drugs for pain relief if it is to be treated. Alternatively, one can choose to use local nerve closure therapy or nerve blocking therapy to relieve the symptoms of local nerve pain. If the nerve pain cannot be relieved by the above treatment, surgical treatment must be given, usually by re-cutting and truncating the fracture and then resetting it to release the compression of the nerve in order to relieve the symptoms at the root.
