What distinguishes acute and chronic sports injuries?
Acute injuries, such as a sprained ankle, strained back, or
fractured hand, occur suddenly during activity. Signs of an acute
injury include: * sudden, severe pain * swelling * inability to
place weight on a lower limb * extreme tenderness in an upper limb
* inability to move a joint through full range of motion * extreme
limb weakness * visible dislocation / break of a bone
