What are the symptoms of a ligament sprain?

Symptoms of ligament strain mainly include the following aspects: 1. Pain: After a ligament strain, patients experience noticeable pain around the joint. The severity of pain correlates with the extent of damage to the ligament and surrounding tissues. The pain may persist continuously and remain present during both activity and rest. 2. Swelling: Due to ruptured blood vessels and bleeding, localized hematoma forms, leading to bruising and swelling under the skin. Pressing on the affected area produces obvious indentation, and pain worsens when moving the injured ligamеnt. 3. Limited mobility: Following a ligament strain, significant pain in the joint area can lead to joint stiffness and restricted movement. Pain markedly increases when attempting to move the injured area, although it may subside somewhat during rest.
