There are two types of contusions: intramuscular and intermuscular contusions.
Intramuscular contusions involve the tearing of the muscle in its sheath. Initial bleeding stops early due to the increased pressure inside the muscle. Any blood is trapped within the sheath and the result is that you won’t see any bruising. One loses proper function in that leg and can be in pain for a few weeks. You will know that you have this type of contusion if the swelling has not gone down within two to three days.

Intermuscular contusions are tearing of the muscle and the sheath around it. If you do not apply ice immediately, bleeding will take a long time to stop. You will see bruising from this type of contusion, but recovery is usually speedier than intramuscular contusions as blood is able to flow freely away from the injury.
If you are able to contract the muscle, you have an intermuscular injury.
If you do not seek help and continue exercising on either kind of contusion, you may inhibit healing and do permanent damage.
There are three different grades of contusions depending on the severity.
Grade one contusions Symptoms
Tightness in the thigh
You can’t walk properly
Little or no swelling
It won’t hurt that much if you straighten your knee
Full range of motion in the knee
What can be done?
R.I.C.E. (Rest, ice, compress and elevate) immediately
Apply a compression bandage or heat retainer until the pain subsides
Do gentle quadriceps stretching five times a day
Grade two contusions Symptoms
You can’t walk properly
Sudden twinges of pain when moving
Slight swelling
It hurts when you apply pressure
It hurts when you straighten your knee
You can’t bend your knee totally
What can be done?
R.I.C.E. (Rest, ice, compress, elevate)
Use crutches for three days at least
Grade three contusions Symptoms
You can’t walk without crutches
Severe pain
Bad swelling
Static contraction of the muscle will be painful and might produce a bulge in the muscle
You will be out of action for three to twelve weeks
What can be done?
Use crutches – you don’t have a choice!
R.I.C.E. (Rest, ice, compress, elevate)
