A sprain occurs when a ligament is stretched or torn. A ligament is a tissue that connects bones at a joint. Sprains can result from falls, twists, or being hit. The most common type of sprain is an ankle or wrist sprain. Pain, swelling, bruising, and the inability to move your joint are among the symptoms. It is possible to feel a pop or tear when an injury occurs.

Strains occur when muscles or tendons are stretched or torn. A tendon is a tissue that connects a muscle to a bone. Strains can occur when these tissues are twisted or pulled. The onset of a strain may be sudden or gradual. The most common muscle strains are back and hamstring strains. Playing sports is a common cause of strains. Pain, muscle spasms, swelling, and trouble moving the muscle are some of the symptoms.
