Icing the bruise, taking pain medication and elevating the bruised area, if possible, are all recommended treatments for a deep bruise, according to WebMD. Resting the area is also recommended to speed up healing.
When icing a bruise, it is best that the area is iced on and off for 24 to 48 hours following the injury, explains WebMD. However, the ice should not be applied directly to the skin, so a towel should be used between the skin and the ice. After two days, heat should be used instead of ice, which further promotes healing. A person can also use an over-the-counter pain reliever to alleviate pain.
If a deep bruise is accompanied by swelling, extreme pain or redness, a person should contact a doctor about the bruise, advises WebMD. A person should also contact a doctor if taking blood thinners, if a bruise appears on the skin without receiving an injury, or if the bruise is on the head or face. If the individual suspects that a bone may be broken or if the joint near the bruise does not move, it is necessary to consult a doctor.
It is important to keep in mind that as a bruise heals, it may change color or spread out, states WebMD. Bruises that are lower on the body, such as the leg, may take longer to heal than a bruise on the arm.
