Muscle strain (pulled muscle) is an overstretching of a muscle. It causes muscle fibers to tear. A muscle strain – often called a pulled muscle – is a common injury that can happen to any muscle in the body, and it can range from mild to severe. A very bad strain can cause a complete muscle tear.

Symptoms:

• Pain or tenderness
• Redness or bruising
• Limited motion
• Muscle spasms
• Swelling
• Muscle weakness
