Rest, Ice, Compression and Elevation. R.I.C.E. can relieve pain, limit swelling and protect the injured tissue, all of which help to speed healing. After an injury occurs, the damaged area will bleed (externally or internally) and become inflamed. Healing occurs as the damaged tissue is replaced by collagen, perhaps better known as scar tissue. Ideally, the scar tissue needs complete repair before a full return to sport is recommended.

After a day or two of R.I.C.E., many sprains, strains or other injuries will begin to heal. But if your pain or swelling does not decrease after 48 hours, make an appointment to see your primary care physician or go to the emergency room, depending upon the severity of your symptoms.
Once the healing process has begun, very light massage may improve the function of forming scar tissue, cut healing time and reduce the possibility of injury recurrence.
Gentle stretching can be begun once all swelling has subsided. Try to work the entire range of motion of the injured joint or muscle, but be extremely careful not to force a stretch, or you risk re-injury to the area. Keep in mind that a stretch should never cause pain.
Heat may be helpful once the injury moves out of the acute phase and swelling and bleeding has stopped. Moist heat will increase blood supply to the damaged area and promote healing.
Finally, after the injury has healed, strengthening exercises can be begun. Start with easy weights and use good form.
