Contusions are bruises of soft tissue that are caused by an object directly striking the body. This trauma will cause bleeding into the tissue, which results in discoloration at the injury site. Other symptoms for contusions include pain and swelling.
Sprains are partial stretching tears of a ligament, which support your body’s joints. The body parts that are commonly sprained in falls and accidents are knees, ankles, and wrists. Sprains are caused by sudden twisting or turning movements. Sprains range in severity from Grade I to Grade III. Grade I sprains involve slight stretching of ligaments; Grade II sprains involve a partial tear of ligaments; and Grade III sprains involve a complete tear of ligaments. Symptoms for all three grades include pain, swelling, and inflammation.
Strains are injuries to a muscle or tendon caused by blunt force or overstretching. In car accidents, the neck, back, and legs are often strained. Strains range from minor to severe. Minor strains occur when the muscle or tendon is overstretched, while severe strains occur when muscle or tendon is partially or completely torn. Symptoms for strains include pain, swelling, inflammation, muscle spasm, muscle weakness, and cramping.
