A torn muscle can frequently result in noticeable swelling and bruising around the affected area. This bruising is caused by bleeding into the tissue, which can be indicated by red, blue, or purple discolouration. A muscle contusion, or bruise, is caused by a direct, blunt blow to the muscle, which crushes muscle fibres and connective tissue without breaking the skin. This can be caused by a fall, a tackle, or a collision during sports. Bruises can be treated at home with rest, ice, compression, and elevation, but more severe contusions may require medical care.

What You'll Learn
Muscle contusion causes
A muscle contusion is a bruise in the muscle. It occurs when an individual receives one or more direct blows to the body part, falls, or jams a body part against a hard surface. The muscles are compressed and crushed between the object or person delivering the blow and the underlying bone. This causes bleeding into the affected muscle, resulting in a sore bruise.
Muscle contusions are more common in people who play contact or extreme sports, such as American football, where a quadriceps (thigh muscle) contusion is one of the most common injuries. However, they can also happen due to falls or traumatic events like car accidents. The most common symptoms of a bruised muscle are pain, bruising, swelling, and difficulty moving the joint near the injury.
Other factors that can increase the risk of a muscle contusion include age, malnutrition, bleeding disorders, and smoking. People over 65 are more likely to develop injuries from falling due to increased risks of malnutrition, weakness, and dizziness. Malnutrition can also cause weakness and dizziness, increasing the risk of falling and getting a muscle contusion. Bleeding disorders, such as hemophilia, can make it more likely for blood vessels to break after an impact, resulting in a muscle contusion. Smoking constricts blood flow and slows healing, which could worsen muscle contusions.
Complications from a muscle contusion can include compartment syndrome and myositis ossificans. Compartment syndrome occurs when pressure rises in and around the muscle due to rapid bleeding, causing painful and dangerous swelling that can decrease blood flow to muscle and nerve cells. Myositis ossificans happen when bone forms inside the muscle after a traumatic injury, usually when the muscle is rehabilitated too quickly.

Treatment for muscle bruising
Bruised muscles, or muscle contusions, are one of the most common sports injuries. They are typically caused by trauma or a blow to the body, which crushes the muscle fibres and connective tissues without breaking the skin. In many cases, a bruised muscle is considered a mild injury, and at-home care is usually enough to treat it. However, severe contusions can lead to deep tissue damage and serious complications.
Most muscle bruises will heal quickly with simple at-home treatments. The RICE protocol is often recommended for the first 24 to 48 hours after injury:
- Rest: Avoid physical activity that may worsen the injury and allow the muscle to rest.
- Ice: Apply ice to the injury to reduce pain, swelling, and bleeding. Do not apply ice directly to the skin; wrap it in a damp cloth and apply for 20 minutes every two hours.
- Compression: Lightly wrap the injured area with a soft bandage to provide support and reduce swelling and bleeding.
- Elevation: Keep the injured area elevated above the level of the heart to reduce swelling.
Over-the-counter nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen, can help with pain relief and reducing inflammation. These should not be used for more than a week.
After the initial acute phase, your doctor may recommend gentle stretching exercises to improve flexibility and restore the range of motion to the injured area. They may also prescribe gentle heat to be applied to the injury. It is important to increase your activity level gradually to avoid further injury and the development of scar tissue.
In the case of severe muscle contusions, medical care may be required. This may include physical therapy, electrotherapy, or, in rare cases, surgery. Your doctor may also recommend a protective device, such as padding or a brace, to prevent further injury when returning to physical activity.

Signs of a torn muscle
A torn muscle, also known as a pulled muscle or muscle strain, is a common but painful injury that can affect anyone. It is caused by pulling a muscle too hard or using it excessively, which weakens the fibres. The signs of a torn muscle include:
Sudden and Severe Pain
The first sign of a torn muscle is usually abrupt and intense pain at the injury site. This pain may occur immediately or develop gradually, depending on the severity of the tear. The pain often worsens with movement or pressure.
Visible Swelling and Bruising
Torn muscles often result in noticeable swelling and bruising around the affected area. Bleeding and inflammation are indicated by red, blue, or purple discolouration. Severe tears may exhibit more pronounced swelling.
Limited Range of Motion
Another common symptom is difficulty or pain when trying to move the injured muscle or joint. Depending on the severity of the tear, there may be weakness or an inability to bear weight on the affected limb.
Muscle Spasms and Popping Sensations
Some individuals report muscle spasms or an audible popping or snapping sensation during the moment of injury.
It is important to note that muscle contusions, or bruises, are different from muscle tears. Contusions are caused by direct blunt force that crushes the muscle fibres without breaking the skin, while muscle tears are caused by overstretching or pulling the muscle fibres. Both injuries can result in similar symptoms, including pain, swelling, and bruising. However, the treatment for a torn muscle may be more extensive, sometimes requiring medical care or even surgery.

Preventing muscle tears
A muscle tear can cause bruising, swelling, and pain. While some muscle tears are unavoidable, there are several measures you can take to prevent them. Here are some tips to help you minimize the risk of muscle tears:
Warm-up and Stretching
Before engaging in any physical activity, ensure you take time to warm up your body. Warming up increases your heart rate and improves blood flow to your muscles, providing them with oxygen. Additionally, stretching before and after a workout or sports activity is essential. Stretching reduces muscle tension, improves flexibility, and provides a better range of motion, helping to prevent muscle tears.
Avoid Overtraining
Overtraining can cause wear and tear on your muscles, increasing the chances of injury. Incorporate rest days into your exercise routine to allow your muscles to recover and heal. Aim for at least two days off from intense exercise each week, and make sure to get plenty of sleep. Proper rest and sleep are crucial for muscle recovery and can help prevent muscle tears.
Stay Hydrated
Dehydration can make your muscles tense and more prone to cramping. When dehydrated, your muscles can't move as well or stretch as far, making them more susceptible to tears. Drink plenty of water to keep your muscles energised and improve their performance. Water also helps your muscles obtain the electrolytes they need to stay healthy.
Strength Training
Strength training can help prevent muscle tears by improving muscle strength and endurance. It is essential to focus on exercises that target various muscle groups, especially those that are more prone to injuries, such as the hamstrings.
Listen to Your Body
Knowing your body's limits is crucial in preventing muscle tears. Pay attention to signs of muscle fatigue or strain and give your muscles the rest they need. Chronic muscle strains can develop gradually, so be mindful of any pain or soreness that persists or develops over time.

Muscle tear recovery
Muscle tears, also known as muscle strains, are injuries that cause stretching of the muscle fibres and can lead to a partial or complete tear of a muscle. The recovery time for a muscle tear depends on the severity, size, and area of injury, but all muscle groups will go through the same general healing pattern.
Immediately after a muscle tear, it is important to immobilize the limb (keep it in one position) with the muscle stretched. For example, a quadriceps (thigh) tear can be immobilized early on with some knee flexion (bending) to keep the muscle constantly stretched. It is also important to apply ice to the injured muscle to minimize swelling. This should be done for about 20 minutes every hour on the first day and then every four hours for the next several days. To reduce swelling, an elastic bandage can be wrapped around the affected area. It is also important to keep the injured muscle raised above the level of the heart whenever possible. Over-the-counter anti-inflammatory medications, such as ibuprofen, can also be taken to help with pain and swelling.
After the first three days, it is important to start applying heat to the muscle several times a day to help bring blood circulation to the area for healing. Gentle stretching exercises should also be started to improve flexibility and restore the range of motion to the injured area. It is important to gradually increase your activity level and not to overdo it, as too much rest can cause muscles to become weak and prolong the healing process.
Most muscle tears will feel less sore and more functional within 6-10 weeks, but the healing process can continue for several months. For severe tears, recovery can take even longer, and surgical repair and physical therapy may be necessary. It is important to follow your doctor's advice and not to return to strenuous physical activity until your muscles have healed to avoid re-injury.

Frequently asked questions
A muscle tear or a "pulled muscle" is an injury that causes stretching of the muscle fibres and can lead to a partial or complete tear of a muscle.
Muscle tears occur when the force across the musculotendinous unit (the connected muscle and tendon) is too great, causing the tissues to tear either partially or completely. This often happens during explosive movements, such as pushing off during a sprint or changing directions in cutting sports.
The symptoms of a muscle tear include sudden pain, swelling, bruising, loss of strength and range of motion. There may also be a popping sound at the time of the injury.
Treatment for a muscle tear depends on the severity of the injury. Most minor tears can be treated at home with rest, ice, compression bandages, and elevation of the injured area. For more severe tears, your doctor may recommend ultrasound or MRI scans to check for internal damage, and in some cases, surgery may be required.
