A thoracic strain, which is sometimes called a mid-back strain, is an injury to the muscles or tendons that attach to the upper part of your back behind your chest. This type of injury occurs when a muscle is overstretched or overloaded.
Thoracic strains can range from mild to severe. Mild strains may involve stretching a muscle or tendon without tearing it. These injuries may heal in 1–2 weeks. More severe strains involve tearing of muscle fibers or tendons. These will cause more pain and may take 6–8 weeks to heal.
This condition may be caused by:
- An injury in which a sudden force is placed on the muscle.
- Exercising without properly warming up.
- Overuse of the muscle.
- Improper form during certain movements.
- Other injuries that surround or cause stress on the mid-back, causing a strain on the muscles.
In some cases, the cause may not be known.
This injury is more common in:
- People with obesity.
The main symptom of this condition is pain, especially with movement. Other symptoms include:
This condition may be diagnosed with a physical exam. X-rays may be taken to check for a fracture.
This condition may be treated with:
- Resting and icing the injured area.
- Physical therapy. This will involve doing stretching and strengthening exercises.
- Medicines for pain and inflammation.
