A ligament sprain occurs when a ligament, which is a band of tissue connecting bones at a joint, is stretched or torn. This injury often happens during activities that involve sudden twists, falls, or impacts, leading to pain, swelling, and limited movement in the affected area. Common sites for sprains include the ankle, knee, and wrist. Treatment for a ligament sprain typically involves rest, ice, compression, and elevation, often referred to as the RICE method. In more severe cases, medical intervention may be necessary, including physical therapy or surgery, to restore function and stability to the joint.
