Bruises are classified as:
- Subcutaneous: A bruise beneath the skin
- Intramuscular: A bruise within a muscle
- Periosteal: A bruise to a bone
Bruises can occur suddenly and last from days to months. Bruises generally cause pain, swelling and tenderness over a black and blue area of skin discoloration. As it heals, it often changes from black and blue to green and yellow.
Treating a bruise is similar to other soft tissue injuries. Using the R.I.C.E method is recommended. Apply ice to the bruise for 15 minutes, several times per day.
Mild contusion or bruises typically heal within about five days.
