A torn muscle, or pulled muscle, occurs when a muscle is overstretched or torn. This can happen as a result of fatigue, overuse, or improper use of a muscle. Torn muscles can cause pain and limit movement within the affected muscle group. Mild to moderate strains can be treated at home with ice, heat, and anti-inflammatory medications, but severe strains or tears may require medical treatment.

| Pain | Mild to moderate strains can be treated at home with ice, heat, and anti-inflammatory medications. Severe strains or tears may require medical treatment. |
| Movement | Mild strains are still flexible enough for use. Severe strains result in very limited movement. |
| Bruising | Visible bruising may be present. |

Mild strains may feel stiff but are still flexible enough for use
A torn muscle, or muscle strain, occurs when a muscle is overstretched or torn, usually as a result of fatigue, overuse, or improper use. Strains can happen in any muscle, but they are most common in the lower back, neck, shoulder, and hamstring.
In more severe cases, the muscle tears into two pieces or shears away from the tendon. This results in significant pain, swelling, and bruising, and very limited movement. You won't be able to use the muscle, and severe strains may require medical treatment or even surgery.
A healthcare provider will usually ask about when the pain started and what you were doing at the time. They will then examine the spot, which may have visible bruising and swelling if it's been at least 24 hours since the injury. They will gently feel it for tenderness and test the muscle for strength and range of motion. A physical exam is often enough to diagnose a pulled muscle, but occasionally an MRI or X-ray may be required to rule out other conditions or to determine the extent of the tear.

Severe strains are very painful and limit movement
A torn muscle can feel stiff but still flexible enough to use. However, a severe muscle strain is when the muscle is severely torn, resulting in pain and very limited movement. You will usually feel a muscle strain as it occurs. In severe cases, the examining physician may be able to feel the defect where the muscle has completely torn. An X-ray may be helpful to rule out a fracture or dislocation as the cause of pain. An MRI can also be used to rule out other conditions or to determine the extent of the tear.

Strains can occur due to fatigue, overuse, or improper use of a muscle
If you have a pulled muscle, you will likely know how it happened. A healthcare provider will ask you about when the pain started and what you were doing at the time. They will then examine the spot, which may have visible bruising and swelling if it has been at least 24 hours since the injury. They will feel the area for tenderness and test the muscle for strength and range of motion. A physical exam is often enough to diagnose a pulled muscle, but in some cases, an MRI may be needed to rule out other conditions or to determine the extent of the tear.
The symptoms of a torn muscle include stiffness, limited movement, and pain. The severity of the strain will determine the extent of these symptoms. In a mild strain, a torn muscle may feel slightly stiff but still flexible enough for use. A severe muscle strain is when the muscle is severely torn, resulting in very limited movement and pain. Grade 2 strains are more serious than grade 1 strains, with less strength and motion in the muscle, and perhaps some swelling and bruising. It may take 2-3 months to recover. Grade 3 strains are the most serious, where the muscle tears into two pieces or shears away from the tendon. The muscle cannot be used, and there is significant pain, swelling, and bruising. This type of injury might need surgery.

Strains are most common in the lower back, neck, shoulder, and hamstring
If you've pulled a muscle, you'll probably know about it. You'll feel pain and may have limited movement within the affected muscle group. A healthcare provider will start by asking you about when the pain started and what you were doing at the time. They'll then examine the spot, which may have visible bruising and swelling if it's been at least 24 hours since the injury. They'll gently feel it for tenderness and test the muscle for strength and range of motion.
The diagnosis is almost always made based on patient history and physical exam. In severe, grade 3 cases, the examining physician may be able to feel the defect where the muscle has completely torn. An X-ray may be helpful to rule out a fracture or dislocation as the cause of pain. While a muscle injury can only be seen on MRI, advanced imaging is often not necessary in the clinical setting as it often doesn't change care.
Mild to moderate strains can be successfully treated at home with ice, heat, and anti-inflammatory medications. Severe strains or tears may require medical treatment. The symptoms of mild to moderate muscle strains usually go away within a few weeks.
