Muscle strains, also known as pulled muscles, are common injuries that can occur due to various activities and circumstances. While some muscle strains can be treated at home, others may require medical attention or even surgery. One factor that can lead to muscle strains is blunt force trauma, which happens when external forces or impacts injure the body. This can occur in several ways, such as through automobile accidents, falls, or collisions with objects or other individuals. The risk of experiencing blunt force trauma can be influenced by factors such as age, flexibility, strength, and the use of protective gear. Understanding the potential causes and risk factors of muscle strains is crucial for implementing preventive measures and seeking appropriate treatment.

What You'll Learn
Muscle contusions (bruises)
A muscle contusion, or bruised muscle, is a painful injury that occurs when a direct blow by a blunt object crushes the muscle fibres and connective tissue without breaking the skin. This results in bleeding into the affected muscle, causing soreness and a bruise.
Muscle contusions are common in contact sports, especially in the upper leg, and are the second most common sports injury after strains. They can also occur due to falls or traumatic events like car accidents, and people over 65 are more likely to develop muscle contusions from falling.
The symptoms of a muscle contusion include swelling, skin bruising, weakness or stiffness in the injured muscle, and difficulty using nearby joints. The severity of the injury will determine the treatment required. Most muscle contusions heal with at-home treatment, such as the RICE (rest, ice, compression, elevation) method. However, more severe contusions may require medical care and can lead to deep tissue damage and serious complications.
If you suspect you have a muscle contusion, you should seek a physical examination from a healthcare provider, who will determine the location and extent of the injury. They may also use imaging tests such as X-rays, ultrasounds, MRIs, or CT scans to assess the soft tissues and check for bone bruises, fractures, or myositis ossificans.
It is important to allow the injury to heal properly and to follow your healthcare provider's advice. Returning to physical activity too soon can lead to further injury.

Compartment syndrome
A "'compartment' is the medical term for a group of muscles, nerves, and blood vessels. Compartments are covered by a fascia — a thin, firm membrane. Compartment syndrome is a serious medical condition that occurs when extra pressure builds up inside a compartment, causing the muscles to press against the fascia more than usual. This pressure can decrease blood flow, which prevents nourishment and oxygen from reaching nerve and muscle cells.
Chronic compartment syndrome, also known as exertional compartment syndrome, happens over time when one exercises too hard or too often. It is usually caused by athletic exertion and is reversible with rest. It is extremely painful but is not usually a medical emergency. It causes pain with exercise, which fades after the activity stops. Other symptoms include numbness, tightness, cramps, weakness, and mild weakness in the affected area. Running and biking commonly trigger chronic compartment syndrome.

Myositis ossificans
During the healing of a bruise, calcium can become deposited, causing a hard, bone-like structure within the muscle. This condition presents as a hard and painful area located at the site of a bruise that has been healing for 2-4 weeks. It can be challenging to distinguish myositis ossificans from osteosarcoma, which can lead to incorrect treatment. An X-ray approximately three weeks after the injury is typically required to confirm the diagnosis of myositis ossificans.
Muscle contusions or bruises are common in contact sports and can result from a direct, blunt blow to the muscle. They are typically treated at home with rest, ice, compression, and elevation (RICE protocol). However, severe contusions can lead to deep tissue damage and complications that may require medical intervention.
Muscle strains, or pulled muscles, are also common injuries that can often be treated at home. They occur when muscle fibres are torn, either suddenly or gradually, through overuse or forceful movements. Treatment depends on the severity of the strain, with severe tears requiring medical care or even surgery.

Treatment for muscle strains
Muscle strains, or pulled muscles, are common injuries that can be treated at home in many cases. However, severe tears may require medical attention or even surgery. Here is a detailed guide on treating muscle strains:
Identify the Severity
The first step in treating a muscle strain is to assess its severity. Muscle strains can be classified as acute or chronic. Acute strains occur suddenly with immediate symptoms, such as a sudden forceful movement or twisting. Chronic strains, on the other hand, develop gradually, and symptoms worsen over time. If you suspect a chronic muscle strain, you may experience gradually increasing pain over several days. For acute strains, the pain is immediate and intense, and you may feel a tearing sensation.
At-Home Treatment
Most minor muscle strains (Grade I) can be treated at home with the RICE protocol:
- Rest: Protect the injured area and rest it. Avoid any activities that may cause further harm.
- Ice: Apply cold packs for 20 minutes several times a day, ensuring you do not place ice directly on the skin.
- Compression: Lightly wrap the injured area with a soft bandage to provide light compression.
- Elevation: Keep the injured area elevated above the level of the heart to control bleeding, swelling, and pain.
Additionally, nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen, can help with pain relief. It is also important to avoid massaging the injured area.
Medical Treatment
For more severe strains (Grade II or III), seeking medical attention is crucial. A healthcare provider will examine the injury, assess its severity, and provide guidance for recovery. They may recommend:
- Physical Therapy: In some cases, gentle stretching exercises may be advised to improve flexibility and aid in recovery.
- Surgery: In rare cases, severe tears may require surgery to repair the damage.
- Platelet-Rich Plasma Injections: This newer treatment uses your own blood platelets to stimulate tissue repair and potentially speed up healing.
Complications
Keep in mind that severe muscle strains can lead to deep tissue damage and serious complications. If you experience any of the following, seek immediate medical attention:
- Severe pain, bruising, or swelling
- Nerve-related symptoms such as numbness, tingling, or sudden weakness
- Compartment syndrome: This is a medical emergency resulting from extremely painful swelling in the muscles, requiring urgent surgery.
Remember, it is always advisable to consult a healthcare professional if you are unsure about the severity of your muscle strain or if your symptoms persist or worsen.

Risk factors for blunt force trauma
- Driving or frequently encountering automobiles.
- Not using safety equipment, such as seat belts, or protective gear, such as helmets, when engaging in activities like sports or cycling.
- Age, especially with decreased balance, strength, or flexibility that occurs naturally over time.
- Occupations or activities that put one at risk, such as working with machinery or large items.
Blunt force trauma can result in a range of injuries, including muscle contusions (bruises), which are common in athletes who play contact sports or participate in extreme sports. The severity of blunt force trauma is influenced by factors such as the force, speed, length of impact, surface area of contact, and elasticity of the impacted tissues.
Motor vehicle crashes are the leading cause of blunt force trauma globally, with pelvic injuries being the most prevalent type of trauma in such incidents. Blunt abdominal trauma (BAT) accounts for 75% of all blunt trauma cases, often resulting from rapid deceleration during a collision. Falls, particularly from heights, are another significant cause of blunt force trauma, especially among the elderly. Direct blows, assaults, and sporting injuries are also common causes.
