There are two types of contusions:
Intramuscular - which is a tearing of the muscle within the sheath that surrounds it. This means that the initial bleeding may stop early (within hours) because of increased pressure within the muscle however the fluid is unable to escape as the muscle sheath prevents it. The result is considerable loss of function and pain which can take days or weeks to recover. You are not likely to see any bruising come out with this type, especially in the early stages.
Intermuscular - which is a tearing of the muscle and part of the sheath surrounding it. This means that the initial bleeding will take longer to stop especially if you do not ice it. However recovery is often faster than intramuscular as the blood and fluids can flow away from the site of injury. You are more likely to see bruising come out with this one.
