Strain (injury)

life science Maturity 5-7 Next article →

A strain is an injury to your soft tissue. This means it happens to a muscle or a tendon. A tendon is the part that connects muscle to bone.

Strains can be acute or chronic. An acute strain comes from a sudden injury or trauma. A chronic strain comes from moving the same way for a long time. These injuries often happen in the foot, the leg, or the back.

Strains work by putting too much stress on your body. This happens when a muscle or tendon overstretches. The tissue might partially tear or even fully break. This often occurs during sudden changes in activity. You might increase how hard you work or how often you move.

Improper body mechanics can also cause this stress. This includes things like lifting heavy objects or playing contact sports. Sometimes the injury is a complete tendon rupture.

Experts use different levels to describe these injuries. The American College of Sports Medicine has three main degrees. A first-degree strain is the mildest kind. It has very little tearing and causes mild tenderness. A second-degree strain involves torn tissues and painful motion. You might see swelling or a small dip at the injury spot.

A third-degree strain is the most severe. This can cause little or no movement at all. In 2012, a Consensus Statement suggested even more ways to classify these injuries. They used terms like functional or structural to help doctors stay uniform.

There are many ways to treat a new strain. One common way is called RICE. This stands for Protection, Rest, Ice, Compression, and Elevation. First, you use soft padding to protect the area. Next, you rest to help the body heal. Ice helps by causing vasoconstriction, which is a way to reduce blood flow.

You should never ice for more than 20 minutes at once. Compression uses a bandage to help with swelling. Finally, elevation means keeping the injury near the level of your heart.

Doctors may also suggest other types of help. Some people use NSAIDs to reduce pain and swelling. These are medicines like ibuprofen or paracetamol. However, these can act as blood thinners. This means they might increase bleeding if the tissue is still bleeding.

A newer treatment is called platelet rich plasma injections. These injections can help people recover faster from certain injuries. You should see a doctor if the pain is very severe. They can check if you have a broken bone or a sprain instead.
