Muscle contusions, or bruises, are one of the most common sports injuries, especially in contact sports such as football, rugby, and lacrosse. They occur when a direct blow or repeated blows by a blunt object strike part of the body, crushing underlying muscle fibers and connective tissue without breaking the skin. Muscle bruises can cause pain, swelling, and limited range of motion of the joint near the injury. In most cases, muscle bruises heal with at-home treatment and do not require surgery. However, severe contusions can cause deep tissue damage and lead to serious complications that may require medical attention.

Causes: Trauma or blunt force to a body part, such as colliding with a hard surface or another person
Bruised muscles, or muscle contusions, are typically caused by trauma or blunt force to a body part. This can occur as a result of colliding with a hard surface or another person, such as during contact sports or a fall. The impact crushes the muscle fibres and connective tissue beneath the skin, causing bleeding within the muscle, which leads to the formation of a bruise. This type of injury is particularly common among athletes, with the thigh being the most common area for muscle contusions, followed by the arm.
Muscle contusions can range from mild to severe. In many cases, they are considered a mild injury and can be treated at home. However, more severe contusions can cause deep tissue damage and lead to serious complications. It is important to seek medical attention if symptoms do not improve within a few days or if there are signs of possible complications, such as rapid swelling or numbness in the affected area.
Contact sports, such as football, rugby, and lacrosse, provide many opportunities for athletes to sustain muscle contusions due to the frequent direct blows or repeated blows by blunt objects. The large thigh muscles, for example, are an easy target during tackling in American football. Strong forces like these can lead to bruises on the muscles without breaking the skin.
In addition to athletes, elderly individuals are also prone to muscle bruising due to an increased risk of falling. Factors such as malnutrition and bleeding disorders can further increase the likelihood of developing a muscle contusion. Falls are not limited to older adults, of course, and can happen to people of any age, potentially resulting in a muscle contusion.
While most muscle contusions heal quickly and without incident, severe cases can have more serious consequences. Deep muscle contusions can occasionally lead to medical complications, such as compartment syndrome and myositis ossificans, which may require surgery. Myositis ossificans is a condition where bone forms inside the injured muscle, reducing flexibility. This complication tends to occur when attempting to rehabilitate a severe contusion too quickly.

Symptoms: Pain, swelling, skin bruising, weakness, stiffness, and difficulty using nearby joints
Bruised muscles, or muscle contusions, occur when there is a direct impact or blow to a muscle, causing damage to the muscle fibers and surrounding tissues. This can result in a range of symptoms, which may vary in intensity depending on the severity of the bruise. Pain is often the first and most prominent symptom. This can be acute and sudden, especially if the contusion is caused by a direct impact or trauma. The pain may be intense and sharp at first and can then develop into a more dull and aching sensation that persists. The affected area will often be tender to touch, and the pain may increase with movement or when putting weight on the muscle.
Swelling is another common symptom of a muscle bruise and usually develops soon after the injury. This is caused by fluid buildup in the damaged muscle tissue and can sometimes result in noticeable lumps or bumps at the injury site. Skin bruising may also be apparent, presenting as a discolored area on the skin, usually in shades of blue, purple, or yellow, indicating bleeding underneath the skin. The severity of the bruising can vary, and it may take several days for the full extent of the bruising to appear.
In addition to pain and swelling, muscle contusions can cause weakness and stiffness in the affected area. Weakness may be experienced when trying to use or contract the injured muscle, and it may feel difficult to perform everyday tasks that usually require minimal effort. This weakness is a result of the damage to the muscle fibers and the associated inflammation, which impairs the muscle's ability to function optimally. Stiffness can also develop, making it difficult to move the joint associated with the bruised muscle through its full range of motion. This stiffness is often worse in the morning or after periods of inactivity.
The combination of pain, swelling, and stiffness can lead to difficulty using nearby joints. For example, a bruised quadriceps muscle in the thigh can make it challenging to bend the knee and perform activities such as walking, running, or climbing stairs. This restricted joint movement is a protective response to prevent further damage and allow the muscle to heal. However, it is important to gradually restore movement to prevent long-term stiffness and mobility issues. Overall, the symptoms of a muscle contusion can vary depending on the severity of the injury, and it is always advisable to seek medical advice if symptoms persist or worsen. Early intervention can help manage pain, reduce swelling, and promote optimal healing to restore muscle function.

Diagnosis: Physical examination, patient history, and imaging tests like ultrasounds and MRIs may be used
A muscle bruise, or muscle contusion, occurs when a direct blow from an object strikes part of the body, damaging the underlying muscle fibres and connective tissue without breaking the skin. Bruises can last from days to months, with bone bruises being the most severe and painful. A muscle bruise can cause pain, swelling, and a limited range of motion of the joint near the injury.
If you suspect you have a muscle bruise, a physical examination by a healthcare provider will help diagnose the injury. They will visually inspect the injury, ask about your symptoms and how the injury happened, and may apply slight pressure to different parts of your injured muscle to determine the exact location and extent of the injury. They may also test the range of motion of nearby joints.
In addition to a physical examination, your doctor may recommend imaging tests to better visualise the inside of the injured area. These imaging tests can include:
- Ultrasound: Ultrasound imaging uses sound waves to capture images of the soft tissues, including muscles and ligaments. It is excellent at picking up signs of swelling and inflammation near joints and muscles.
- Magnetic Resonance Imaging (MRI): MRI is a non-invasive scanning technology that uses magnetic fields and radio waves to generate detailed digital images of organs, soft tissues, bones, and other internal body structures. MRI scans of muscles help physicians identify the best site to perform a muscle biopsy if needed.
- Computed Tomography (CT) Scan: CT scans use X-ray images taken from various angles to provide an in-depth look at the interior of the body. They are often used to diagnose problems with bones or muscles.
- X-rays: X-rays are typically used as an initial imaging test to visualise bones and can be followed by additional tests if further evaluation is required.
Your doctor may also recommend other diagnostic tests, such as blood tests, to aid in diagnosing the muscle bruise and determining the appropriate treatment plan.

Treatment: At-home care, such as RICE (rest, ice, compression, and elevation), is often enough, but severe cases may require medical care
Bruised muscles, or muscle contusions, are typically caused by trauma or a blunt force blow to the body. This crushes the muscle fibres and connective tissue beneath the skin without breaking it. Bruised muscles can usually be treated at home, but more severe cases may require medical care.
At-home treatment for muscle bruises typically involves the RICE protocol: Rest, Ice, Compression, and Elevation. Rest the injured muscle by stopping play and protecting the area from further harm. You may also use a protective device such as crutches or a sling. Apply ice to the injured area to reduce pain and swelling. Wrap the injured area in a soft bandage or ace wrap to help ease swelling. Finally, elevate the injured area to a level above the heart.
It is important to note that you should not put ice directly on your skin. Instead, wrap the ice in a washcloth or paper towel. Additionally, do not massage the injured area, as this can make the injury worse.
While at-home care is usually sufficient for muscle bruises, moderate to severe cases may require medical attention. If you experience worsening symptoms or your injury does not show signs of improvement, seek medical advice. Left untreated, severe muscle injuries can result in serious medical complications, such as compartment syndrome or myositis ossificans.

Complications:
Muscle contusions are very common, especially in athletes and elderly individuals. In many cases, a bruised muscle is considered a mild injury and can be treated at home. However, severe contusions can lead to serious tissue damage and complications.
One such complication is myositis ossificans, a condition in which bone forms inside the injured muscle. This can develop after a severe muscle contusion if the patient tries to rehabilitate too quickly. Myositis ossificans can cause reduced flexibility, and in some cases, the bone may have to be surgically removed. Compartment syndrome is another potential complication, which may require urgent surgery to drain excess fluids. This can occur when rapid bleeding causes extremely painful swelling within the muscle group of the arm, leg, foot, or buttock.
In addition to these specific complications, severe contusions can cause deep tissue damage, limiting an athlete's ability to play sports for months. Furthermore, if the tissue damage is extensive, there may be a broken bone, dislocated joint, sprain, torn muscle, or even damage to internal organs if the impact was to the abdomen.
It is important to seek medical attention if symptoms do not improve within a few days or if there are signs of possible complications, such as rapid swelling or numbness in the affected area.

Frequently asked questions
Bruised muscles are typically caused by trauma or a blunt force blow to a body part. This trauma crushes the muscle fibres but doesn't break the skin tissue. Bruised muscles are often the result of direct contact sports, a hard fall, or colliding with a hard surface. Symptoms include pain, swelling, and skin discolouration.
At-home care is usually enough to treat most muscle bruises. You can apply ice wrapped in a clean towel to the bruised area to help it heal faster and reduce swelling. Keep the bruised area raised above the heart if possible, to keep blood from pooling in the bruised tissue. Rest the bruised body part and take acetaminophen (Tylenol) to help reduce pain.
Bruised muscles are typically mild injuries that heal quickly. However, if your symptoms don't improve within a few days, or you experience numbness, weakness, or rapidly increasing swelling in the injured area, you should seek medical attention.
