The consequences of<unk> range from mild pain for a few days (which is the case for most people), to severe disability. It seems that around 50% will have some remaining symptoms. Alterations in resting state cerebral blood flow have been demonstrated in patients with chronic pain after<unk> injury. There is evidence for persistent inflammation in the neck in patients with chronic pain after<unk> injury. There has long been a proposed link between<unk> injuries and the development of temporomandibular joint dysfunction (TMD). A recent review concluded that although there are contradictions in the literature, overall there is moderate evidence that TMD can occasionally follow<unk> injury, and that the incidence of this occurrence is low to moderate.
