While it may be tender and sore, a bruise, also known as a contusion, is generally considered a minor injury. The term bruise refers to harm to soft tissue and blood vessels, or bleeding under the skin, when the skin has not been broken. The blood collects in one area and is marked by a change in skin color and often by inflammation. A severe bruise, on the other hand, may be an indicator of a more serious problem.

Common bruises are often referred to as “black and blue” marks, but a fresh, minor bruise will usually appear pink or red at first and then change to light blue or purple. A severe bruise will be darker, and may in fact appear black and blue, as well as dark purple, and may be rather swollen. As a bruise heals, the colors change and can turn green, brown, or yellow.

Deep bruising with swelling is often treated first with ice or some form of cold therapy. After the first 24 to 48 hours, heat may be applied. Bruise cream can aid in healing bruises and relieving pain more quickly as well as improving appearance.


A serious bruise often occurs as the result of an injury such as a sprain or a broken bone. The bone itself may also be bruised. Bruising can also be caused by illness, especially blood diseases. If swelling increases, if the bruise is very painful, or if it does not begin to improve after a week or two, it is a good idea to see a doctor.

In most cases, bruises will not require medical attention. Elevating the injury, using ice packs or a heating pad, and applying a topical cream may be all that is necessary. With a severe bruise, however, paying close attention to any changes is important.

The location of a severe bruise can also be an indicator of a more serious medical problem. A bruised navel may indicate internal bleeding. Bruising behind the ears or around the eyes can be a sign of head injury, which can indicate many issues from concussion to brain injury or skull fracture. These types of bruising should be evaluated by a health-care provider immediately.

A severe bruise that begins to feel hard or continues to grow instead of healing should also be checked out. A severe bruise that fits this description is often referred to as a hematoma. While the body will generally absorb the hemorrhaged blood over time, sometimes it will need to be drained. Draining may be necessary to aid in healing as well as to avoid infection.

I lost my temper about five days ago and punched a wall a couple times. My middle metacarpal knuckle almost immediately turned purple and swelled up a lot. It faded to a large, light green bruise but now it's turning bright red. I haven't hit anything else and I've been wrapping it up. Is something going wrong?

I've noticed that applying ice to an injury within the first few minutes helps prevent and reduce bruising. It can prevent a bruise from turning black.

@ZipLine-- If you get severe, deep tissue bruises very easily, then there might be some other problem. You should see your doctor about it and get some blood tests to make sure that everything is okay.

Falling off a bike can definitely cause severe bruises. But if you also get severe bruises from minor injuries, such as bumping on a desk, then it's a sign of an underlying health problem.

My nephew used to get severe bruises from just about anything and was diagnosed with a blood disorder soon after. Thankfully, he's fine now.

Vitamin K is said to be very helpful for severe bruises. Dark purple bruises can take forever to heal and fade. Vitamin K cream apparently helps speed up the process.

I'm planning on buying some because I tend to bruise frequently. I fell off my bike last month and ended up with severe bruising on my leg. It took forever to fade away.
