Muscle contusions, or bruises, are a common injury, especially among athletes in contact sports. They are caused by a direct blow or repeated blows from a blunt object, which crush underlying muscle fibres and connective tissue without breaking the skin. Bruised muscles typically cause pain and swelling, and can limit joint range of motion near the injury. In most cases, muscle bruises are mild and can be treated at home, but severe contusions can cause deep tissue damage and lead to serious complications, such as compartment syndrome and myositis ossificans, which may require surgery.

What You'll Learn
Muscle contusions are bruises
Most muscle contusions are minor and heal quickly with at-home treatment, without taking the athlete away from the game. At-home care is usually enough to treat most muscle bruises. To control pain, bleeding, and inflammation, keep the muscle in a gentle stretch position and use the RICE protocol: Rest, Ice, Compression, and Elevation. During the first 24 to 48 hours after injury, continue using rest, ice, compression bandages, and elevation of the injured area to control bleeding, swelling, and pain. Your doctor may give you non-steroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen, or other medications for pain relief.
However, severe contusions can cause deep tissue damage and lead to complications that may prevent an athlete from playing sports for months. Compartment syndrome and myositis ossificans are two of the more common complications that can occasionally result from deep muscle contusions. In certain cases, rapid bleeding may cause extremely painful swelling within the muscles of the arm, leg, foot, or buttock. Build-up of pressure from fluids several hours after a contusion can disrupt blood flow and prevent nourishment from reaching the muscle group.

Bruised muscles can be caused by trauma or blunt force
Bruised muscles, or muscle contusions, are injuries to muscle fibres and connective tissues. They are often caused by trauma or blunt force to a body part. This could be the result of a fall, a collision with a hard surface, or a tackle during a contact sport. The impact crushes the muscle fibres and connective tissue beneath the skin, causing bleeding and bruising. Bruised muscles can cause pain, swelling, and limited joint range of motion near the injury.
Muscle contusions are a common injury in contact sports such as American football, where athletes are at risk of sustaining direct blows or repeated blows from blunt objects. They can also occur in extreme sports, such as falling on top of someone or colliding with another person. In many cases, a bruised muscle is considered a mild injury, and athletes may continue playing with proper protection and pain management.
However, severe contusions can cause deep tissue damage and lead to serious complications. Compartment syndrome, for example, occurs when there is internal bleeding and rapid, painful swelling within a muscle group. This can compromise blood flow to other areas, causing tissue death and potentially requiring emergency surgery. Myositis ossificans is another possible complication, where the injured muscle grows bone cells instead of muscle cells during the healing process, leading to reduced flexibility and range of motion.
To treat a bruised muscle, it is important to control pain, bleeding, and inflammation. This can be achieved through the RICE protocol: Rest, Ice, Compression, and Elevation. Gentle stretching exercises can also be introduced a day after the injury to improve flexibility. In most cases, muscle contusions heal well with time and may not require surgery. However, severe cases may warrant medical attention to avoid permanent muscle damage and ensure proper healing.

Bruises can cause pain, swelling and skin discolouration
Bruises can cause pain, swelling, and skin discolouration. A bruise occurs when blood leaks out of your veins and capillaries and pools under your skin. This can happen when blood vessels break or leak, causing blood to seep out and pool underneath your skin. Bruises can form a mark on your skin that ranges in colour from black, blue, purple, brown, or yellow. They can also be identified by discoloured skin that is tender to touch.
Bruises can be the result of blunt force or trauma to the body, which is common in contact sports. A muscle contusion is a bruise in your muscle, caused by a direct, blunt blow. This can result from colliding with a hard object or another person, crushing the muscle fibres and connective tissue beneath the skin. While the skin does not break from the blow, the impact can cause internal bleeding, leading to pain, swelling, and discolouration.
The main symptoms of a bruise are pain, swelling, and skin discolouration. Bruises can last from days to months, and more severe bruises may require treatment. Resting and elevating the injured area can help prevent swelling and relieve pain. Applying ice can also reduce pain, swelling, and bleeding. In some cases, doctors may prescribe anti-inflammatory medication to speed up recovery.
In addition to pain, swelling, and discolouration, bruised muscles can cause limited joint range of motion near the injury. Severe contusions can result in deep tissue damage and lead to complications that may require athletes to refrain from sports for extended periods. It is important to seek medical advice and follow the recommended treatment plan to ensure proper healing and prevent further injury.

Compartment syndrome is a rare complication of bruising
A bruised muscle, or muscle contusion, is an injury to the muscle fibres and connective tissues. It is often caused by a direct, blunt blow to a muscle, which crushes the muscle fibres without breaking the skin. Bruised muscles are common in athletes, particularly those who play contact sports, but they can also occur as a result of falling or colliding with a hard surface.
Acute compartment syndrome is the most common type of compartment syndrome and is considered a medical emergency. It usually develops rapidly over a few hours after a serious injury to the arm or leg, although it can also occur in other parts of the body such as the thigh, buttocks, hands, and feet. It is often caused by a broken bone or severe muscle sprain or bruise, and can result in loss of function or amputation of the affected area if left untreated.
Chronic compartment syndrome, also known as exertional compartment syndrome, is usually less severe and is not typically a medical emergency. It is often caused by athletic exertion or regular, vigorous exercise such as running, swimming, or biking. It is reversible with rest and usually involves the lower leg, buttock, or thighs.
Although rare, compartment syndrome is an important complication to be aware of in the case of bruising or muscle contusions. It can have serious consequences if not treated promptly and effectively.

Myositis ossificans can occur after a severe muscle contusion
A muscle contusion is a bruise in the muscle, caused by a direct, blunt blow to the muscle. It is the second most common sports injury, especially in contact sports. In most cases, muscle contusions are minor and heal quickly. However, severe contusions can cause deep tissue damage and lead to serious complications.
Myositis ossificans is a rare, benign condition that can occur after a severe muscle contusion. It is characterised by the formation of bone within the injured muscle tissue, also known as heterotopic ossification. This happens when the body, during the healing process, creates new bone cells instead of muscle cells. It typically affects large muscles in the arms or legs and can cause a painful, tender lump.
Myositis ossificans usually develops two to four weeks after a severe muscle injury, often following a traumatic injury or repeated trauma to the same muscle. It can result in severe functional impairment and disability without appropriate diagnosis and treatment. The condition should be suspected when the degree of pain and soft tissue swelling is disproportionate to the original injury.
To diagnose myositis ossificans, a healthcare provider will physically examine the injury, assess symptoms, and test the range of motion of nearby joints. Imaging tests such as X-rays, MRIs, and ultrasounds may also be used to confirm the presence of bone formation within the muscle.
While there is no guaranteed way to prevent myositis ossificans, the risk can be reduced by properly treating severe bruises and swelling. The RICE method (Rest, Ice, Compression, Elevation) is recommended immediately after injury to control pain, bleeding, and inflammation.

Frequently asked questions
A muscle contusion is a bruise in the muscle. It occurs when a direct blow or blunt force crushes the muscle fibres and connective tissue beneath the skin without breaking the skin.
The symptoms of a muscle contusion include pain, swelling, and limited range of motion of the joint near the injury. The injured muscle may feel weak and stiff. In some cases, there may also be bleeding beneath the skin, which can cause shock if severe enough.
Most muscle contusions can be treated at home with rest, ice, compression, and elevation (RICE protocol). Over-the-counter medications such as ibuprofen can help with pain relief. In severe cases, medical attention may be required to avoid complications, and surgery is sometimes necessary.
Athletes in contact sports are particularly susceptible to muscle contusions, as they frequently involve direct blows or collisions. Elderly individuals are also at higher risk due to an increased risk of falling.
