What is a haematoma?

A hematoma (or haematoma) is a collection or pool of blood that has leaked and clotted outside of blood vessels, often forming a lump under the skin or deeper within tissues, organs, or body spaces, usually due to injury, surgery, or disease. While simple bruises are superficial hematomas, more significant ones can be serious, causing swelling, discoloration, and pressure on surrounding structures, requiring monitoring or treatment, especially if internal, like in the brain, where symptoms can include severe headaches, confusion, or vision changes.

Is a hematoma serious?

A hematoma happens when you have blood pooling someplace inside your body. Most hematomas aren't serious, and you can commonly see them in the form of surface bruises. But when hematomas are deeper or bigger, they can become serious.

How do you treat a hematoma?

Hematoma treatment depends on severity, with small ones often managed at home with RICE (Rest, Ice, Compression, Elevation) and over-the-counter pain relievers (avoiding NSAIDs if on blood thinners). Larger or severe hematomas, especially internal ones or those on the head, need medical evaluation for drainage, surgery (like embolization for brain hematomas), addressing underlying causes (like stopping anticoagulants), or managing complications, notes Cleveland Clinic and National Institutes of Health (NIH).
 

How long does a haematoma take to go away?

A hematoma is not a bruise. It is a pooling of blood outside of the blood vessels deeper in the skin than a bruise occurs. Trauma is the most common cause of a hematoma. Depending on the cause, it can take anywhere from 1 to 4 weeks for a hematoma to go away.

What does haematoma look like?

A hematoma looks like a swollen, painful lump or a deep bruise with significant discoloration (red, purple, blue, or black) that changes color as it heals, often feeling firm and tender, unlike a flat bruise, because blood pools and clots under the skin or deeper in the body. It can appear as a raised "goose egg" on the surface or be internal, causing swelling, pain, and potential nerve issues, changing from reddish-brown to green and yellow as it reabsorbs.
 

Hematoma, Causes, Signs and Symptoms, Diagnosis and Treatment.

What is the most common cause of a hematoma?

Physical trauma

Direct injury is the most frequent cause of a haematoma. This may include: Falls, especially in older adults or children. Blunt force to any part of the body, such as from sports, accidents, or assault.

What is the fastest way to dissolve a hematoma?

The fastest way to dissolve a hematoma involves initial ice (cold therapy) and RICE (Rest, Ice, Compression, Elevation) for the first 48 hours to reduce swelling, followed by switching to warm compresses and gentle massage after 48 hours to promote blood flow and reabsorption, with severe or large hematomas sometimes requiring medical drainage. Time is essential as the body reabsorbs the blood, but proper care helps speed the process and manage symptoms. 

What should you not do with a hematoma?

When dealing with a hematoma, avoid applying direct heat, vigorous massage, or strenuous activity, and do not take aspirin or ibuprofen as they increase bleeding; instead, use R.I.C.E (Rest, Ice, Compression, Elevation) and seek immediate medical care for serious signs like worsening pain, altered consciousness, or infection. 

How to know if a hematoma needs to be drained?

A hematoma needs draining if it's large, painful, growing, infected, or puts pressure on vital structures like organs or nerves, causing functional impairment or intense discomfort, with drainage often done via needle or minor surgery to relieve pressure and prevent complications like abscesses or tissue death. Small hematomas usually resolve on their own, but significant ones, especially those under a nail or in deep tissues, may require prompt medical drainage.
 

What are the stages of a hematoma?

Soft: Following an injury, the hematoma feels soft initially because there is a buildup of new blood beneath the skin or in the muscular tissue. The hematoma may get firmer as the blood starts to clot, which is a normal stage of the healing process. Firm: The clot may become hard or lumpy over time.

Is a hematoma a blood clot?

The pooling blood gives the skin a spongy, rubbery, lumpy feel. 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. Follow-up care is a key part of your treatment and safety.

Can a hematoma heal without draining?

Most hematomas are harmless and not a cause for concern. They usually resolve over time as the blood clot is removed and the blood vessels are repaired. However, some hematomas need surgical drainage depending on the location and symptoms.

When to worry about a bruise?

You should worry about a bruise if it's unexplained, unusually large, very painful, doesn't fade within two weeks, or is accompanied by severe swelling, numbness, heat, redness, pus, fever, vision changes, or occurs after head trauma. Seek immediate care for symptoms like intense pressure in a limb, signs of infection (streaks, drainage), or bruising after a fall with suspected broken bones or head injury.
 

What are the red flags of a hematoma?

Unlike superficial bruises, subdural hematomas do not show on the skin but instead cause severe headaches, nausea, slurred speech, vision changes, dizziness, weakness, memory loss, or personality changes. Symptoms can appear immediately, within hours, or even weeks after an injury.

What happens if you leave a hematoma untreated?

Leaving a hematoma untreated can lead to severe complications like infection, nerve damage, compartment syndrome, or pressure on vital organs, potentially causing permanent disability or even death, especially for internal or deep hematomas, as the pooled blood can form clots, cause inflammation, and disrupt normal function. While minor skin hematomas might resolve, serious cases need medical attention for potential drainage or intervention to prevent worsening conditions like brain damage (from intracranial hematomas) or shock.
 

What is the best hematoma treatment?

Treatment for Hematoma

This typically involves rest, elevation of the affected area, and applying ice packs or cold compresses to reduce swelling and pain. Over time, the body's natural healing processes will gradually reabsorb the blood and resolve the hematoma.

When to worry about a hematoma?

Signs of infection may include increased pain, redness, warmth, swelling, or the presence of pus. Prompt medical attention is necessary to diagnose and treat infections associated with hematomas. Increased Pressure: As a hematoma expands, it can exert pressure on surrounding tissues, organs, or structures.

What does a concerning hematoma look like?

A bad hematoma looks like a swollen, painful lump with significant skin discoloration (red, purple, blue, or black) that may feel hard, and it can cause nerve symptoms like numbness or tingling, restricted movement, and intense pain, differing from a simple bruise by its distinct lump and greater severity, especially if it's deep or near vital structures like the brain. Signs of infection (pus, warmth, red streaks) or severe neurological issues (severe headache, confusion, vision changes) mean it's a medical emergency.
 

What can be mistaken for a hematoma?

Soft tissue hematoma is a common clinical condition following trauma. Although it typically regresses over time, a hematoma could enlarge and may be mistaken for a tumor [6,7]. Conversely, soft tissue tumors may be misdiagnosed as hematomas because of their similar clinical and imaging features [8].

What are the complications of a hematoma?

The swelling and inflammation of the tissues surrounding the broken blood vessel can irritate organs and tissues in the surrounding area, causing widespread pain and additional inflammation and swelling. Hematoma injuries also present a significant risk for infection.

How do you tell if a lump is a hematoma?

Hematomas and bruises have slightly different qualities: a bruise is flat and causes the injured area on the skin to turn black and blue. Meanwhile, a hematoma, if superficial enough to be visible, creates a painful, lump on the skin that can be red, black, blue or purple.

What are the risk factors for hematomas?

Some conditions also may increase the risk of having an intracerebral hematoma. They include being born with poorly connected arteries and veins, and having a bulging blood vessel in the brain, known as an aneurysm. High blood pressure, tumors and some diseases also increase the risk.

How long does it usually take for a hematoma to go down?

The swelling and pain of the hematoma will go away. This takes from 1 to 4 weeks, depending on the size of the hematoma. The skin over the hematoma may turn bluish then brown and yellow as the blood is dissolved and absorbed. Usually, this takes only a couple of weeks but can last months.

What not to do with a hematoma?
