How long does it take for a bruise to form?
When a bruise first happens, it's kind of red as the blood appears under the skin. Within 1–2 days, the hemoglobin (an iron-containing substance that carries oxygen) in the blood changes and the bruise turns bluish-purple or even black. After 5–10 days, the bruise looks green or yellow.
Bruises often begin as a red mark on the skin because fresh, oxygen-rich blood has pooled under the skin. After 1-2 days the blood that has leaked out begins to lose oxygen and change color. Depending on the size, location and severity of your bruise, it could appear shades of blue, purple or black.
It often starts red because fresh, oxygen-rich blood has newly pooled underneath the skin. After around 1–2 days, the blood begins to lose oxygen and change color. A bruise that is a few days old will often appear blue, purple, or even black. In about 5–10 days, it turns a yellow or green color.
This process makes your bruise change colors: It's usually red right after the injury. Within a day or two, it turns purplish or black and blue. In 5 to 10 days, it may be green or yellow.
Should You Ice a Bruise? Absolutely. An ice pack, bag of ice, or anything frozen placed on an injury when it occurs helps reduce the amount of blood that leaks from the blood vessels into the surrounding tissues. Putting ice on a fresh bruise can prevent severe discoloration.
In surviving victims, a deep bruise may not become apparent on the skin until several hours or even days later because of the slow percolation of free blood from the original site to superficial tissue layers.
To minimize bruising, it's best to elevate the injured area and apply ice immediately after impact. Preventive action is the best way to avoid bruises, so consider de-cluttering household items, and use safety gear if you're doing something that could be harmful to your body.
You may want to massage the sore spot when you're resting, but it's a bad idea. That can make the injured spot worse. You may break more blood vessels under the skin and make the bruised area larger.
Initially, they're reddish. Then, they'll often turn dark purple or blue after a few hours. As the bruise heals, it will typically become green, yellow, or lime. A bruise is usually painful at first and may feel tender.
Can't bad bruises cause blood clots? The bruise itself won't cause a blood clot. In very rare circumstances, the hit that caused the bruise can. If a deep-seated vein is damaged during the collision, it could lead to a deep-vein clot.
How long does a bruise hurt?
Bruises that result from trauma are usually tender to the touch and may be slightly swollen. Bruises vary in their healing time from a few days to several weeks, depending on how severe they are. A moderate bruise typically takes around 2 weeks to fade away entirely.
As the bruise heals, the color of the bruise will change, becoming red, green, or yellow before it disappears. Bruises just under the skin are called “subcutaneous.” They can also occur within muscles. If they occur on bones, they're referred to as “periosteal.” More bruises tend to be subcutaneous.

Vitamin K clarifying cream is recommended. A pulse dye laser can be used to help clear bruises within 24 to 48 hours after the bruise appears. Arnica gel is an herbal remedy that has proven to help reduce inflammation and bruising.
Wrapping the bruised area with an elastic bandage such as an Ace wrap will help decrease swelling. Don't wrap it too tightly, as this can cause more swelling below the affected area.
It is believed that toothpaste helps break up the clot and increase blood flow. People report noticing a difference after just one night, but it may take several applications to make the bruise completely disappear.
Myositis ossificans.
A deep muscle bruise or repeated trauma to the same muscle can cause your muscle tissues to harden and form bone. This complication can dangerously affect your range of motion.
Once you have iced the bruise for 24 hours, you should start applying heat to the bruised area. This will increase circulation to the affected area and help to break down the pooled blood. An electric heating pad works best and should be used for 20 minutes several times throughout the day.
The color change is due to the biochemical breakdown of hemoglobin that is found in the blood. As the different components of the blood are broken down, different colors will appear in the bruise.
Most bruises aren't serious, and they'll disappear completely within about two weeks. To minimize bruising, it's best to elevate the injured area and apply ice immediately after impact.
In surviving victims, a deep bruise may not become apparent on the skin until several hours or even days later because of the slow percolation of free blood from the original site to superficial tissue layers.
What looks like a bruise but doesn't hurt?
Blood spots under the skin may be either purpura or petechiae. Purpura might look like bruises, but they are not caused by an injury as most regular bruises are.
Not only will ibuprofen help with the pain, it will help reduce swelling and subsequent bruising, as well.
