Different sports injuries produce different symptoms and complications. The most common types of sports injuries include:

• Sprains. Overstretching or tearing the ligaments results in a sprain. Ligaments are pieces of tissue that connect two bones to one another in a joint.
• Strains. Overstretching or tearing muscles or tendons results in a sprain. Tendons are thick, fibrous cords of tissue that connect bone to muscle. Strains are commonly mistaken for sprains. Here’s how tell them apart.
• Knee injuries. Any injury that interferes with how the knee joint moves could be a sports injury. It could range from an overstretch to a tear in the muscles or tissues in the knee.
• Swollen muscles. Swelling is a natural reaction to an injury. Swollen muscles may also be painful and weak.
• Achilles tendon rupture. The Achilles tendon is a thin, powerful tendon at the back of your ankle. During sports, this tendon can break or rupture. When it does, you may experience sudden, severe pain and difficulty walking.
• Fractures. Bone fractures are also known as broken bones.
• Dislocations. Sports injuries may dislocate a bone in your body. When that happens, a bone is forced out of its socket. This can be painful and lead to swelling and weakness.
• Rotator cuff injury. Four pieces of muscle work together to form the rotator cuff. The rotator cuff keeps your shoulder moving in all directions. A tear in any of these muscles can weaken the rotator cuff.
