Muscle contusions, more commonly known as muscle bruises, are a common injury in sports and occur when a person sustains a direct blow or blunt force trauma to the body. This force crushes the underlying muscle fibres and connective tissue without breaking the skin, causing bleeding to occur and become trapped under the skin, resulting in bruising. Muscle bruises can cause pain, swelling, and a limited range of motion in the affected joint. Depending on the severity of the injury, muscle bruises can take days or months to heal and may require physical therapy to aid in recovery.

Muscle bruises are caused by a blow to the body, fall, or blunt force trauma
Muscle bruises, also known as muscle contusions, occur when a blow from an object strikes a part of the body, damaging and causing bleeding in the underlying muscle fibres and connective tissue without breaking the skin. The skin not being broken means that the bleeding is trapped under the skin, causing discolouration and bruising.
Muscle bruises are commonly caused by a blow to the body, fall, or blunt force trauma. This can happen during everyday activities, such as hitting your thigh on the corner of a desk or falling on a hard floor. They are also very common in sports, especially contact sports like football, where athletes are prone to direct blows or blunt force trauma.
The symptoms of a muscle bruise include pain, swelling, skin discolouration, muscle weakness and stiffness, and a limited range of motion in the joint near the injury. In severe cases, muscle bruises can cause deep tissue damage, which may take several weeks or even months to heal and can lead to complications such as compartment syndrome or myositis ossificans if not properly treated.
If you suspect you have a muscle bruise, it is recommended to follow the RICE procedure: Rest, Ice, Compression, and Elevation. Over-the-counter pain relievers can also be taken to improve comfort. For severe muscle contusions, it is important to seek medical attention, as you may require physical therapy, surgery, or other treatments to aid in healing and prevent complications.

Symptoms include pain, swelling, skin discolouration, and reduced range of motion
A muscle bruise, or muscle contusion, occurs when a direct blow or blunt force trauma damages the underlying muscle fibres and connective tissue without breaking the skin. This type of injury is common in sports and can occur as a result of a fall or direct impact during vigorous activities. Symptoms of a muscle bruise include pain, swelling, skin discolouration, and reduced range of motion, which will be detailed further in the following paragraphs.
Pain is a common symptom associated with muscle bruises due to the underlying muscle fibre and connective tissue damage. The severity of pain can vary depending on the extent of the injury, with severe contusions causing deep tissue damage that may require medical attention and physical therapy for proper healing.
Swelling is another symptom that can be observed with muscle bruises. This occurs due to bleeding under the skin, where blood leaks from small vessels crushed by the impact. While most muscle bruises are minor and heal quickly, severe cases of swelling may require emergency medical care to drain excess fluid and release muscle pressure, preventing complications such as compartment syndrome.
Skin discolouration is a noticeable symptom of muscle bruises due to trapped blood under the skin. The bruise colour changes over time, often starting as a red or purplish mark, turning blue or black, then green or yellow, and finally fading to brown before disappearing completely. These colour shifts occur as the body breaks down and reabsorbs the leaked blood.
Reduced range of motion is a symptom that can be experienced due to the pain, swelling, and stiffness associated with muscle bruises. In some cases, the injury may limit the ability to fully move a nearby joint or perform certain activities, especially with more severe contusions that cause deep tissue damage. Physical therapy may be recommended to help improve range of motion and build strength during the recovery process.

Treatment includes rest, ice, compression, and elevation (RICE), and anti-inflammatory medication
Muscle bruises, or muscle contusions, occur when a direct blow from an object strikes part of the body, damaging the underlying muscle fibres and connective tissue without breaking the skin. The main symptoms of a muscle bruise are pain, minor swelling, and skin discolouration. The changes in skin colour are due to trapped blood under the skin, which the body breaks down and gets rid of over time.
Treatment for muscle bruises includes rest, ice, compression, and elevation (RICE), and anti-inflammatory medication. Rest involves taking a break from the activity that caused the muscle bruise. Applying ice wrapped in a cloth to the affected area for 15-20 minutes can provide relief. Compression can be achieved by applying a soft bandage to the injured area. It is also important to elevate the injury site above heart level to promote healing.
Additionally, your doctor may prescribe non-steroidal anti-inflammatory drugs to reduce pain and inflammation. These medications can help speed up the healing process and manage any discomfort associated with the injury. In some cases, physical therapy may be recommended to help improve strength and flexibility in the affected area. This is especially important for severe contusions to prevent complications such as compartment syndrome and myositis ossificans, which can occur without proper medical treatment.
The healing time for a muscle bruise can vary depending on the severity of the injury. Minor contusions can heal quickly, while severe contusions with deep tissue damage can take several weeks or even months to fully recover. It is important to be patient and allow the body to heal, as most contusions will improve with time and proper care.

Severe bruises may require surgery to drain excess fluid and speed up healing
A muscle bruise, or muscle contusion, occurs when a direct blow from an object strikes part of the body, damaging and crushing the underlying muscle fibres and connective tissue without breaking the skin. Muscle bruises are common in sports and can occur as a result of a direct blow or from falling or jamming against a hard surface. They can be minor or severe. Minor contusions can be managed with at-home care and do not affect an athlete's ability to play.
However, severe muscle bruises can cause deep tissue damage and may require medical care. They can also lead to complications, such as broken bones, joint dislocation, torn muscles, sprains, and shock due to swelling and bleeding under the skin. Abdominal contusions may even result in internal organ damage. In the case of a large hematoma, surgery is performed to drain the fluid and speed up the healing process. Compartment syndrome, which can occur when pressure rises in and around the muscle, is another potential complication of severe muscle contusions. It is a medical emergency and may require urgent surgery to relieve the pressure and prevent serious damage. Myositis ossificans is another possible complication, where bone forms inside the muscle after a traumatic injury.
To treat a muscle bruise, it is recommended to follow the RICE protocol: rest, ice, compression, and elevation. Gentle stretching exercises can also help improve flexibility. In most cases, surgery is rarely required for muscle bruises.

Complications from severe bruises include compartment syndrome and myositis ossificans
A muscle bruise is an injury that occurs during vigorous activities, often sports. It happens when a direct blow from an object strikes part of the body, damaging the underlying muscle fibres and connective tissue without breaking the skin. Symptoms include swelling, pain, skin discolouration, and a limited range of motion of the joint near the injury. Severe muscle contusions can cause deep tissue damage and may take up to a month or more to heal.
Complications from severe bruises can include compartment syndrome and myositis ossificans. Compartment syndrome is a painful buildup of pressure around the muscles, which restricts blood flow and causes pain. It happens when an injury or repeated stress causes swelling and bleeding inside a muscle compartment. If the pressure builds too much, the muscles press against the fascia (a thin, firm membrane that covers a compartment) and start squeezing against the muscles and nerves. This squeezing causes pain and other symptoms. Acute compartment syndrome is a medical emergency that occurs after severe injuries or as a surgery complication. It can cause permanent muscle damage, paralysis, or even death if not treated immediately. Chronic compartment syndrome, on the other hand, happens over time with intense exercise or physical activity.
Myositis ossificans is a condition that occurs when bone tissue forms in soft tissues or muscles. It is a reaction to a bruise in a muscle that has been injured. During the healing process, calcium can become deposited in the bruise, forming a hard, bone-like structure within the muscle. This condition usually affects large muscles, such as those in the arms or legs, and is more common in young, active people and athletes. The exact reason for myositis ossificans is unclear, but it often occurs when the body doesn't make the right cells during the healing process, creating new bone cells instead of muscle cells. The most common sign of this condition is a large, painful, tender lump beneath the skin, which can reduce the range of motion if it grows near a joint.
