Muscle strains, also known as pulled muscles, are common injuries that affect the muscles and ligaments. They occur when the force on a muscle is too great, causing the tissue to be damaged and resulting in stretching or tearing of the muscle fibres. When a muscle is initially injured, inflammation and swelling occur, followed by the regeneration of muscle fibres and the formation of scar tissue. While most muscle strains can be treated at home, severe tears may require medical care or surgery.

What You'll Learn
Pulled muscles are muscle tears
A pulled muscle, or muscle strain, is a tear in the muscle fibres. It is one of the most common soft tissue injuries and can be caused by pulling a muscle too hard or overusing it, which weakens the fibres. When a muscle is strained, the strands of fibre are stretched beyond their limit and tear apart. This can happen suddenly with a forceful movement or twist, or it can develop gradually over time.
Muscle strains can be acute or chronic. Acute strains happen suddenly and cause immediate symptoms, while chronic strains develop over time, and the symptoms develop gradually. Acute strains often occur during activities that require explosive movements, such as sprinting or changing directions in cutting sports. The force across the musculotendinous unit (the connected muscle and tendon) can be so great that the tissues tear, either partially or completely.
Chronic strains, on the other hand, develop over time due to overuse without sufficient time for repair. This can happen, for example, during training camps when athletes are suddenly increasing their exercise regimens or when muscles are overfatigued. In both cases, the muscle fibres are stretched beyond their limit and tear apart, resulting in a pulled muscle or muscle strain.
Muscle strains can be mild to severe. A mild strain, or Grade 1 muscle strain, involves stretching and pulling the muscle enough to cause minor damage, but it is not completely torn through. A severe tear, or Grade 3 muscle strain, tears all the way through the muscle. Severe tears may require medical care or even surgery, while mild strains can often be treated at home.
When a muscle is initially injured, significant inflammation and swelling occur. This is followed by the inflammatory phase, during which the muscle begins to heal by regenerating muscle fibres. However, scar tissue also forms where the muscle was injured, and this can make the muscle more prone to future injury.

They cause swelling and pain
A pulled muscle, or muscle strain, is a common injury that occurs when the force on a muscle is so great that the tissue is damaged, causing a partial or complete tear in the muscle fibres. They are usually painful and can cause swelling.
When a muscle is initially injured, significant inflammation and swelling occur. This is followed by the muscle healing itself by regenerating muscle fibres. However, scar tissue forms where the injury occurred, and this can make the muscle more prone to future injury.
The amount of pain and swelling depends on the severity of the injury. A grade 1 muscle strain is a mild injury with minimal impact on muscle strength or movement. A grade 2 strain is more serious, causing a noticeable loss of strength and movement, as well as some swelling and bruising. A grade 3 strain is a severe injury, where the muscle tears into two pieces or shears away from the tendon. This can cause significant swelling and pain, and may require surgery.
If you suspect you have a pulled muscle, it is important to stop moving the affected area to prevent further injury. You can try keeping the pulled muscle elevated and take pain relievers to reduce pain and improve mobility.

They can be mild or severe
A pulled muscle, or muscle strain, is a common injury that occurs when muscle fibres are stretched beyond their limit, resulting in a tear. This can range from a mild strain with minimal impact on muscle strength to a severe tear that may require medical attention or even surgery.
When a muscle is initially pulled or strained, significant inflammation and swelling occur. This is followed by the regeneration of muscle fibres and the formation of scar tissue. While most pulled muscles can be treated at home, severe tears may require medical care to ensure a smooth recovery.
The severity of a pulled muscle can vary from mild to severe. A grade 1 muscle strain is a mild injury with minimal impact on muscle strength or motion. It involves only a few fibres being pulled and broken. A grade 2 strain is more serious, resulting in reduced muscle strength and motion, and possibly some swelling and bruising. It may take several months to recover from a grade 2 strain.
A grade 3 muscle strain is a severe injury where the muscle tears into two pieces or shears away from the tendon. This type of strain can result in a lengthy healing process and a complicated recovery. An X-ray or MRI may be necessary to assess the extent of the injury and rule out other issues such as fractures or blood clots.
It is important to note that even mild pulled muscles can cause significant pain and discomfort. If you suspect you have pulled a muscle, it is recommended to stop moving the affected area and consult a healthcare provider if the pain persists.

They can be treated at home
A pulled muscle, also known as a muscle strain, is a soft-tissue injury resulting from tears in your muscle fibres. It is one of the most common soft tissue injuries. When you strain a muscle, the strands of fibre are stretched beyond their limit and tear apart. This can be caused by pulling the muscle too hard, overusing it, or not warming up correctly.
A pulled muscle can be very sore and painful. Pain from a pulled muscle may feel uncomfortable, sore, or sharp. Pulled muscle pain can range from mild discomfort to severe pain that worsens with certain positions and movements. Mild cases can generally be treated with at-home treatments, while severe cases may require surgery or medical care.
If you have a pulled muscle, you will likely experience significant inflammation and swelling. This swelling, along with the pain, can be treated at home. Here are some remedies to consider:
- Heat and cold therapy: Heat therapy encourages blood circulation and relaxes the muscles. Cold therapy, such as ice packs, reduces pain perception, increases the pain threshold, and may reduce bruising and swelling by constricting blood vessels, slowing nerve conduction velocity, and preventing fluid build-up around the injury.
- Over-the-counter (OTC) pain relievers: These are great for short-term use and may be used alongside other holistic forms of treatment.
It is important to note that not all strains are alike, and a severe tear might need medical care or even surgery. If you heard or felt a "pop" when your muscle tore, if you can't move your muscle at all, or if pain, bruising, and swelling are severe, seek medical attention right away.

Severe tears may need surgery
A pulled muscle, or muscle strain, is a common injury where the muscle fibres are stretched beyond their limit and tear apart. This can happen as a result of exhaustion, improper use, or overuse. While any muscle can be strained, pulled muscles most often occur in the lower back, neck, shoulder, and hamstring.
Pulled muscles can be classified as mild, moderate, or severe. Mild strains involve stretching and pulling the muscle enough to cause minor damage, but without tearing through the muscle fibres. Moderate strains involve tearing through some or most of the muscle fibres, affecting muscle strength and range of motion. Severe strains, or grade III strains, involve a complete tear of the muscle fibres.
Most people can recover from a pulled muscle at home using the RICE method (Rest, Ice, Compression, and Elevation). However, severe muscle tears may require surgery to repair the damage. The type of surgery recommended will depend on the level of pain, the type of injury, and the amount of damage. For example, acute tears may qualify for less invasive surgery, while traditional surgery with a large open incision may be necessary when there is a large amount of damage to the muscle, tendon, cartilage, ligaments, and/or bone fractures.
During surgery for a complete muscle tear, the surgeon will make one long incision in the area of the muscle injury. They will then reattach the torn muscle to the tendon or sew the torn edges of the muscle together using sutures. A small screw or anchor may be used to reattach the tendon or muscle to the bone if it has been completely ruptured. Surgeons typically use strong nylon or polyester material to bring the edges of the torn muscle together, employing a locking-loop or three-loop pulley pattern to prevent the muscle tissue from gapping.
In some cases, percutaneous surgery may be performed using small incisions or "stab incisions" to free the soft tissue and stitch or suture any tears. This type of surgery is often successful in improving the range of motion and is commonly used when previous open surgeries have been unsuccessful and there is a build-up of scar tissue.

Frequently asked questions
A pulled muscle, or muscle strain, is a common but painful injury that occurs when the force on a muscle is so great that the tissue is damaged, causing a partial or complete tear of the muscle.
Yes, a pulled muscle can cause swelling. The amount of swelling depends on the grade of the muscle strain. A grade 1 muscle strain is a mild strain with minimal impact on muscle strength or motion and may not cause much swelling. A grade 2 muscle strain is more serious and can cause swelling and bruising, while a grade 3 muscle strain is a severe injury where the muscle tears into two pieces.
Most pulled muscles can be treated at home with rest, pain relievers, and elevation of the affected area. However, it is important to stop moving the affected area to prevent further injury. If the pain persists after 24 hours, consult a doctor.
To prevent a pulled muscle, it is important to properly warm up before any physical activity and gradually progress your exercise intensity. Additionally, ensure that you allow for adequate recovery time between workouts to give your muscles time to repair.
