What should I do for a sprained hand ligament?

After a wrist ligament strain, the following measures should be taken to promote recovery: 1. **Emergency treatment**: Immediately stop any activity to avoid further injury. Within the first 48 hours after injury, apply ice packs to the affected area for 10–20 minutes at a time, multiple times daily, to reduce swelling and pain. 2. **Immobilization and elevation**: If the injury is severe, wrist immobilization or casting may be required, typically for 3–4 weeks. At the same time, elevate the injured arm above heart level to help reduce swelling. 3. **Medication**: If symptoms such as pain and swelling are severe, medications such as blood-activating and stasis-resolving agents or anti-inflammatory analgesics may be used under a physician's guidance, including topical applications or oral nonsteroidal anti-inflammatory drugs (NSAIDs). 4. **Physical therapy**: After removal of the external immobilization, physical therapies such as heat application, massage, and infrared irradiation may be performed to promote blood circulation and aid ligament recovery. Specific treatment should be based on the severity of injury and the physician's recommendations.
