what does it mean when you sprain something
Sprain A sprain, also known as a torn ligament, is damage to one or more ligaments in a joint, often caused by trauma or the joint being taken beyond its functional range of motion. The severity of sprain ranges from a minor injury which resolves in a few days to a major rupture of one or more ligaments requiring surgical fixation and a period of immobilization. Sprains can occur in any joint but are most common in the ankle and wrist.[1]
Congenital insensitivity to pain Congenital insensitivity to pain (CIP), also known as congenital analgesia, is one or more rare conditions in which a person cannot feel (and has never felt) physical pain.[1] The conditions described here are separate from the HSAN group of disorders, which have more specific signs and cause. Because feeling physical pain is vital for survival, CIP is an extremely dangerous condition.[1] It is common for people with the condition to die in childhood due to injuries or illnesses going unnoticed.[1][2] Burn injuries are one of the more common injuries.[2]
