As a bruise heals, the body breaks down blood and fluids that have accumulated under the skin. As this happens the bruise turns different colors.
What does a black bruise mean?
Blood leaks into tissues under the skin and causes the black-and-blue color. As bruises (contusions) heal, usually within 2 to 4 weeks, they often turn colors, including purplish black, reddish blue, or yellowish green. Sometimes the area of the bruise spreads down the body in the direction of gravity.

How long does a bruise take to heal?
Within the first five days the hemoglobin inside the blood changes and the bruise turns into the color of a bluish-purple or even black. Between five and ten days, the bruise usually becomes slightly green or yellow. Then, after 10 or 14 days, it finally becomes a yellowish-brown or light brown.

Why do I have a blue bruise?
Red blood cells leak out of these blood vessels. These red blood cells that collect under your skin cause that bluish, purplish, reddish, or blackish mark. That's where black-and-blue marks get their name — from their color under the skin. Bruises go through colorful changes as the body begins to heal itself.

How long is too long for a bruise to last?
Within 1 or 2 days, the hemoglobin (an iron-containing substance that carries oxygen) in the blood changes and your bruise turns bluish-purple or even blackish. After 5 to 10 days, the bruise turns greenish or yellowish. Then, after 10 or 14 days, it turns yellowish-brown or light brown.
5
What does green mean in a bruise?
Bruises close to the surface in people with light-toned skin will often look black or blue initially because of the blood accumulating under the skin. However, over time the pigment in blood begins to break down and turn from black/blue to yellow/green shades.
6
Why is my bruise yellow and purple?
Initially, a bruise is red because the hemoglobin in your blood is full of oxygen and iron. It's responsible for the green hue of the bruise that often appears a few days after the injury. As your bruise fades, it takes on a yellow tint. This is because the biliverdin breaks down and produces bilirubin.
7
Do blood clots look like bruises?
A regular bruise is more spread out and may not feel like a firm lump. A hematoma usually is not a cause for concern. It is not the same thing as a blood clot in a vein, and it does not cause blood clots. Bruises that do not appear to be caused by an accidental injury may be caused by abuse.
8
Why is my bruise purple?
Within a day or so of impact, your bruise will darken to blue or purple. This is caused by both low oxygen supplies and swelling at the bruising site. As a result, hemoglobin, which is typically red, begins a gradual change to blue. This darkening can last through the fifth day after injury.

What is a small hematoma?
Hematoma is generally defined as a collection of blood outside of blood vessels. Most commonly, hematomas are caused by an injury to the wall of a blood vessel, prompting blood to seep out of the blood vessel into the surrounding tissues.
10
Is a hematoma serious?
Is a hematoma serious? A hematoma is seldom serious. A hematoma results from an injury that causes blood vessels to rupture. The blood that seeps from the damaged blood vessels cannot escape and pools in the soft tissue.
11
Can hematoma cause death?
Complications of subdural hematoma. Complications of subdural hematomas may occur soon after the injury or sometime after the injury has been treated. These complications may include: brain herniation, which puts pressure on your brain and can cause a coma or death.
12
Is hematoma bad?
A hematoma is a larger collection of blood, usually caused by surgery, injury, or a greater trauma. Hematomas will usually reabsorb into the body, like a bruise. However, depending on the size, location and cause of the hematoma, the area may need to be drained surgically, or take a longer period of time to resolve.
13
Do subdural hematomas go away?
As is the case with any brain injury, symptoms can be slow to go away after treatment. Some symptoms may be permanent. Occasionally, a subdural hematoma is small enough that you may not need surgery to remove the blood. The blood will be reabsorbed gradually by the body.
14
What are the symptoms of a slow brain bleed?
Symptoms of subdural hematoma can include:
- Headache.
- Confusion.
- Change in behavior.
- Dizziness.
- Nausea and vomiting.
- Lethargy or excessive drowsiness.
- Weakness.
- Apathy.
15
How does a subdural hematoma cause death?
This type of subdural hematoma is among the deadliest of all head injuries. The bleeding fills the brain area very rapidly, compressing brain tissue. This often results in brain injury and may lead to death. Subdural hematomas can also occur after a minor head injury.
16
Is a contusion the same as a hematoma?
Hemorrhage is active or ongoing bleeding. A hematoma is a pathologic collection of blood in body tissues, outside of blood vessels. A contusion is a type of hematoma in which blood has escaped from ruptured capillaries and is interspersed into surrounding tissue, usually due to trauma.
17
What are the symptoms of hitting your head too hard?
Here are the symptoms of a concussion that should prompt an immediate trip to the hospital or emergency department.
- Loss of consciousness, even if only briefly.
- Any period of amnesia, or loss of memory for the event.
- Feeling dazed or confused.
- Headache.
- Vomiting.
- Seizure.

Can you die in your sleep if you have a concussion?
Myth 1: Fall asleep with a concussion and you might die. Not so, says David Hovda, M.D., a professor of neurosurgery and director of the UCLA brain-injury research center. After trauma occurs, it's important to watch for the signs of a life-threatening brain injury: double vision, dizziness, and nausea or vomiting.
19
Can you sleep if you hit your head?
Answer: There is no benefit to keeping someone awake after a concussion, and it is no longer recommended. In fact, people with a concussion need to sleep to recover. Anyone getting very sleepy within six hours of a brain injury should be brought immediately to an emergency department for a head CT scan.
