Sprains, strains, and fractures are all painful types of injuries. Sprains occur at joints and involve the overstretching or tearing of ligaments, which are fibrous connective tissues that hold together two bones. The ankle, wrist, knee, thumb, and back are the most frequent locations where sprains can happen. Strains, on the other hand, are a result of muscles and tendons being stretched out and torn. The most commonly affect the hamstring muscle in the upper leg or muscles in the lower back. Tendons are also made of fibrous connective tissues, but they join bones to muscles. Fractures are not related to injuries in tissues, but instead are breaks within the bone. The leading causes of fractures are auto accidents, falls, or sports-related trauma. Conditions that result in the weakening of the bones such as osteoporosis can be a predisposing factor for injury-related fractures.
