injuries

Yesterday I suffer a injury while training fast repetitions on the track. I think it is a contusion. I search web for some indications for treatment:

Contusions occur when a direct blow or repeated blows from a blunt object strike part of your body, crushing underlying muscle fibers and connective tissue without breaking the skin.
First aid

Contusions cause swelling and pain and limit joint range of motion near the injury. Torn blood vessels may cause bluish discoloration. The injured muscle may feel weak and stiff. To control pain, bleeding and inflammation, keep the muscle in a gentle stretch position and use the R.I.C.E. formula:
* Rest: Protect the injured area from further harm by stopping play. You may also use a protective device (i.e., crutches, sling).
* Ice: Apply ice wrapped in a clean cloth. (Remove ice after 20 minutes.)
* Compression: Lightly wrap the injured area in a soft bandage or ace wrap.
* Elevation: Raise it to a level above the heart.

Treatment

Most athletes with contusions get better quickly without surgery. Your doctor may give you nonsteroidal anti-inflammatory drugs (NSAIDS) or other medications for pain relief. Do not massage the injured area. During the first 24-48 hours after injury (acute phase), you will probably need to continue using rest, ice, compression bandages and elevation of the injured area to control bleeding, swelling and pain. While the injured part heals, be sure to keep exercising the uninjured parts of your body to maintain your overall level of fitness. If you have a large hematoma that does not go away within several days, in some cases the doctor may drain it surgically to speed healing.
