A wrist injury can involve either a sprain or a strain.
Sprains result from suddenly stretching or tearing the ligaments that hold the bones together.
A strain is an injury to the muscles or the tendons that connect the muscles to the bones. In most cases, either type of injury will take about 6 to 8 weeks to heal. Causes Sprains are usually caused by an accident. Strains usually result from over-use. Typically, there will be pain, tenderness, swelling, or bruising of the injured wrist.
