Bruises that Itch: Possible Causes and Treatments

Bruises that itch

A bruise is a common skin injury which can appear due to trauma. A trauma can be a cut or blow to any part of the body. It results in discoloration of the skin.

Blood from damaged blood cells, deep beneath the skin, collects near the surface of the skin. It leaves a black and blue mark on the skin.

Bruises that itch and won’t go away are generally those bruises which are in the healing process.

The body clears the pooled blood under the skin. The accumulation of bilirubin in a bruise, as it heals, causes the area to itch.

A bruise that itches is a common phenomenon. You need not panic about it unless it is intense and shows symptoms like swelling or fever. There are several ways to treat itching bruises but let us first see how they are formed.

How are Bruises Formed?

It is foremost important to understand how bruises that itch form. Bruises form when the tiny blood vessels, also known as capillaries, in the skin break.

It may happen as a result of traumatic injury or vigorous exercise. The blood collects in the tissues around the vessels.

In the beginning, bruises don’t itch. They develop as pink or red colored discoloration in the skin due to hemoglobin. Bruises gradually develop a blue or purple color within few hours. It indicates the falling level of oxygen in the pooled blood.

Within five days, a chemical compound named biliverdin forms. It forms due to biochemical breakdown of hemoglobin. The bruises turn to greenish color.

Then comes the final healing stage. The bruises turn to pale yellow or brown depending on the level of bilirubin. The rising level of this chemical compound can cause a deep bruise to itch.

Possible Causes of Bruises that Itch

Why do bruises itch? The primary cause of a bruise as already discussed is trauma or vigorous exercise. Unexplained bruising can appear on thigh, leg, arm, or back that later turn itchy.

The bruises in leg take more time to heal than the arm or other parts. Sometimes the bruise can occur without any injury. Some causes for such itchy bruises are:

1. Old Age

Your skin contains a fatty tissue layer. It supports the blood vessels against external infringements. You lose a part of this tissue layer, and your skin turns thinner as you grow old.

Therefore, the older adults are more prone to bruises. The sun damage on the skin for years can also give rise to bruises that itch even due to walking.

2. Blood Disorder

Leukemia can also cause a deep bruise to itch when the reason for it isn’t apparent. It is a condition which reduces the ability of the body to produce platelets.

Leukemia can cause a bruise to appear in unlikely parts of the body like back. If nose bleed accompanies bruises that itch, see a doctor immediately.

3. Liver Diseases

Liver cirrhosis, hepatitis, and other problems may cause bruises that itch and won’t go away. These conditions cause inflammation in the liver.

They reduce the ability to clot and so the patient becomes more prone to bruises.

4. Genetic Issues

Bruises that itch can be genetic too. Unexplained itchy bruises can occur if you are born in a family with a history of the same.

5. Vascular Diseases

There are two types of vascular conditions which can lead to bruises that itch. One of them is purpuric dermatosis in which small bruises appear on the skin resembling cayenne pepper.

Another one is vasculitis in which bruises appear on the back of legs and thighs.

6. Blood-Thinning Medications

Warfarin, aspirin, and antiplatelet agents are also responsible for itchy bruises. They reduce the ability of blood clotting.

Such medications can lead to excessive bleeding. Women who use contraceptives can develop a bruise that itches and won’t go away quickly.

Women tend to bruise more on the upper arms, thighs, and buttocks than other parts.

7. Supplements

Supplements like fish oil also have a similar effect on capillaries like the blood-thinning medicines.

Fish oil is a rich source of omega-3, docosahexaenoic acid (DHA), and eicosapentaenoic acid (EPA). It treats conditions like high blood pressure, painful menstruation, and depression.

8. Corticosteroids

Corticosteroids treat allergies, asthma, and similar diseases. They make the skin thinner and make it more vulnerable to developing bruises.

If you are on corticosteroids and you develop itchy bruises without an injury, consult a doctor.

A bruise will heal gradually if caused by an injury or trauma. Consult a doctor if you develop a bruise that occurs for no apparent reason.

Sometimes itching can lead to bruises. Common causes include fungal infections, dry skin, or insect bites. Women can develop itchy bruises when pregnant. Allergy and other factors are also responsible for the same.

Are Bruises that Itch a Sign of Underlying Problems?

Bruises that itch and won’t go away easily indicates skin problems, but you shouldn’t ignore them. Sometimes, it can be a more significant issue. It is primarily a reason to worry if it comes with symptoms like fever, dizziness, and swelling.

Bruises that itch can also be a sign of a liver condition known as Primary Biliary Cirrhosis (PBC). It damages the bile ducts in the liver. It is also responsible for inflammation and loss of bile ducts.

Bile and toxic wastes pile up in the liver. It leads to the development of scar tissues in the liver. It is a condition known as liver cirrhosis. The continued gradual buildup of scar tissues ultimately leads to liver failure. It can thus, necessitate a liver transplant.

The exact cause of PBC is not known. When the immune system attacks the bile ducts, PBC may develop. Alcohol and diet too may affect it.

Some people are more prone to PBC due to their inherited genes. Women have a higher risk of developing this autoimmune disease than men.

Smoking, infections, and contact with toxic compounds can also trigger primary biliary cirrhosis.

If you have persistent itching and unexplained bruising, seek medical attention immediately.

People suffering from primary biliary cirrhosis may suffer from various symptoms. Common symptoms are fatigue and dry eyes and mouth. They can also suffer from the altered sleeping pattern (sleepless nights and sleep days) and dizziness.

To treat PBC, doctors administrate medications to slow down the progression of liver damage. So don’t consider itchy bruises as only a skin problem.
