Sprains are when you tear or stretch a ligament, whereas strains are when you tear or stretch a muscle or tendon. Ligaments are the tissue that connect the bones in a joint. Tendons are tissues that connect muscle to bones.
Sprained ankles and wrists occur most frequently and you may even hear a pop or tear when the sprain occurs. You will notice swelling, pain, bruising, and you will likely have a hard time moving your joint. These usually occur from falling, or twisting.
Strains occur when you overexert a muscle or tendon, lift the wrong way, or have a recent injury. They also can occur over time by using it the same way over and over. Strains will have some different symptoms than sprains. There may still be pain and swelling, but also the muscle might be weak, spasming, cramping, or unable to move.
Guidelines for treatment for both strains and sprains from the National Institute of Health say to:
