What is a sprain?

A sprained hand or wrist is an injury that occurs when you fall or catch your hand, causing it to move or be pulled in an awkward way. This can stretch or damage the tough bands of tissue (ligaments) that help hold your bones together.
Ligaments help stabilise joints, preventing excessive movement. A sprain occurs when the ligaments are forced beyond their normal range of motion.
Treatment for a sprain depends on the severity of the injury but most recover well with a little time to recover and then simple rehab exercises once the pain has settled.
