Muscle strain, also known as a pulled muscle, is a common but painful injury that causes stretching and tearing of muscle fibres. It can lead to swelling and bruising, which are signs of inflammation. This injury can be caused by over-exertion or sudden, forceful movements. While muscle strains are often treated at home, they can sometimes require medical intervention or even surgery. This article will explore the link between muscle strain and inflammation, the treatment options available, and preventative measures to avoid future injuries.

What You'll Learn
Muscle strain severity
Grade II strain is a moderate strain, with a greater number of injured fibres and more severe muscle pain and tenderness. There is also mild swelling, noticeable loss of strength and sometimes a bruise. It may take 2-3 months to recover.
Grade III strain is a severe injury where the muscle tears into two pieces or shears away from the tendon. There is significant pain, swelling, and bruising. A complete muscle tear (muscle rupture) might need surgery to repair it. A severe grade III strain can take four to six months to heal after surgery.
The severity of a muscle strain and the function or load that the injured muscle must cope with will impact the length of the healing and rehabilitation process. Muscle strains can be caused by a sudden increase in duration, intensity, or frequency of activity, and they can occur during everyday tasks, although athletes are more at risk.

Anti-inflammatory medication
Muscle strain, or a pulled muscle, is an injury that causes the stretching of muscle fibres and can lead to a partial or complete tear in the muscle. It can also damage small blood vessels, causing local bleeding or bruising. When you strain a muscle, the muscle fibres get damaged, and inflammation sets in along with a blood clot, which is similar to an internal scab. The inflammatory cells absorb and get rid of the damaged cells.
Non-steroidal anti-inflammatory drugs (NSAIDs) such as Naproxen and Ibuprofen are effective in relieving muscle pain. They are often used for the pain and disability associated with stretch-induced muscle injuries, muscle contusions, and delayed-onset muscle soreness (DOMS). However, there is no convincing data that NSAIDs improve healing or recovery time. In fact, there are some small studies that suggest NSAIDs may impede healing in acute injury settings and could result in modest inhibition of the initial inflammatory response. Corticosteroids have also been shown to adversely affect the healing of acute injuries.
Acetaminophen is another medication that lessens pain but does not reduce inflammation.
It is important to note that muscle strains are common injuries, and most can be treated at home with rest and light stretching. For more serious injuries, a doctor may recommend surgery or alternative treatments such as chiropractic or osteopathic manipulation, acupuncture, or myofascial release, which is a type of massage.

Muscle strain treatment
Muscle strains, or pulled muscles, are common but painful injuries. They occur when muscle fibres are stretched beyond their limit and tear apart, causing damage to the muscle or its attaching tendons. This can result in local bleeding or bruising and pain due to irritated nerve endings in the muscles.
Most muscle strains can be treated at home, but sometimes they require medical care. If you suspect a serious muscle injury, it is important to seek medical attention. Symptoms of a severe muscle strain include hearing or feeling a "pop" when the muscle tore, an inability to move the muscle, severe pain, bruising, and swelling. Nerve-related symptoms such as numbness, tingling, sudden weakness, or difficulty controlling certain muscles may also indicate nerve damage.
For minor muscle strains, rest is essential to allow the muscle to heal. It is important to stop moving the affected area to prevent further injury. Once the pain has improved, light stretching and easy activities can be introduced gradually. However, it is crucial not to overdo it, as resting for too long can lead to stiffness and weakness.
To manage pain, anti-inflammatory medication can be used, although there is limited evidence that NSAIDs (nonsteroidal anti-inflammatory drugs) improve healing or reduce recovery time. Acetaminophen is another option that lessens pain without reducing inflammation. Platelet-rich plasma injections, a newer treatment, use platelets from the patient's own blood to stimulate tissue repair, but more research is needed to prove their effectiveness.
In some cases, surgery may be recommended, especially for complete muscle ruptures. Surgery can help repair the muscle, but scar tissue formation at the injury site increases the susceptibility to future injuries.

Muscle strain causes
Muscle strain, also known as a pulled muscle, occurs when a muscle is stretched too far, leading to a partial or complete tear in the muscle or its attaching tendons. Tendons are fibrous tissues that attach muscles to bones. Strains can happen suddenly or develop over time from overuse.
Athletes, runners, dancers, and adolescents are particularly susceptible to muscle strains. Athletes are at risk when they suddenly increase their exercise regimens or when their muscles are overfatigued. Adolescents are vulnerable because their bones and muscles grow at different rates, causing muscles to tighten as bones lengthen.
Muscle strains can also occur during everyday tasks, such as heavy lifting or sudden movements. Certain muscles are more prone to injury, including the hamstrings, gastrocnemius, quadriceps, hip flexors, hip adductors, Erector Spinae, deltoid, and rotator cuff.
To prevent muscle strains, it is important to properly warm up and stretch before physical activity. Regular stretching can help to loosen muscles, making them more flexible and less likely to tear. Additionally, maintaining muscle balance by ensuring that opposing muscle groups have similar strength can reduce the risk of strain.

Muscle strain diagnosis
Doctors often classify muscle strains into three grades, depending on the severity of muscle fiber damage:
Grade I Strain
In this mild strain, only a few muscle fibers are stretched or torn. The injured muscle is tender and painful, but it has normal strength and a minimal impact on motion.
Grade II Strain
This is a moderate strain, with a greater number of injured fibers, more severe muscle pain, and tenderness. There is also mild swelling, a noticeable loss of strength, and sometimes a bruise. The muscle will have less strength and motion.
Grade III Strain
This strain indicates a complete rupture of the muscle, tearing it all the way through. It causes a complete loss of muscle function, considerable pain, swelling, and tenderness. There may be an obvious "dent" or "gap" under the skin where the ripped pieces of muscle have separated.
For more serious muscle strains, doctors may use an ultrasound to check for tears or fluid, or an MRI to check for blood clots, internal bleeding, or other issues. However, MRI is typically recommended only when necessary for diagnosis, as most muscle strains are treated conservatively.
It is important to note that muscle tearing does not always require imaging to diagnose, and physical therapy can aid in reducing tear-related symptoms and improving muscle health.

Frequently asked questions
A muscle strain, or pulled muscle, is a common but painful injury that occurs when a muscle is stretched too far or tears.
Common symptoms include pain, swelling, and limited movement. Other symptoms include bruising, redness, and muscle spasms.
Yes, muscle strains can cause inflammation. Torn muscles can result in noticeable swelling and bruising around the affected area, indicating inflammation.
Most muscle strains can be treated at home using the RICE method (rest, ice, compression, and elevation). For more severe strains, medical treatment may be required, including surgery in some cases.
Proper warm-ups and regular stretching can help prevent muscle strains.
