An acute injury is generally an injury that is severe and with sudden onset. Sprained ankles, strained backs, and fractured hands are acute injuries. Acute injury is a sudden injury that is usually associated with a traumatic event such as clashing with another player during sports or a fall from a bike.
A traumatic impact can cause your bone to crack, muscles to tear or ligaments to snap. You will experience a sudden sharp pain that is often severe, immediate swelling and even cold purple regions in your body that indicates a lack of proper blood circulation in that injured part. You may even lose your stability if your knee ligaments are torn and you will be unable to place your body weight on it. Those are prime examples of what an acute injury is.
Acute injury is usually the result of a specific impact or traumatic event that occurs in one specific area of the body, such as tearing a muscle, breaking a bone, or injury to the joint. Acute pain from an injury issue typically requires immediate medical attention. If you suspect your injury is severe, you should go to the emergency department. The following symptoms may be a sign of a severe injury that requires professional care: severe swelling and pain, crunching or popping sound from the injured area, visible deformities, and inability to support weight on the injured area, trouble breathing, fever, or dizziness.
Otherwise, some acute pain or injuries can be treated at home with the rice treatment. Rest, ice the area, compress or immobilize the injured area, and elevating the injured area above the heart will minimize swelling and pain. You should also see a doctor for further evaluation if after you have tried treatment at home using the rice method and you are still having pain or instability.
