How to quickly reduce swelling and relieve pain from a hand injury

　　Generally speaking, there is no such thing as "how to quickly reduce swelling and pain from a swollen hand after hitting it." When a hand becomes swollen from impact, swelling and pain can be reduced through appropriate measures such as immobilization, ice compresses, heat compresses, elevating the affected limb, and medication. The specific methods are as follows:

　　1. Proper immobilization: Immobilizing the injured area reduces movement, prevents further injury, and minimizes worsening of the swelling. You can use tape or gauze to wrap and immobilize the area, or wear an aluminum splint or paper collar to restrict finger movement.

　　2. Ice compress: Applying an ice compress causes blood vessels to constrict, reducing local tissue bleeding and swelling while also alleviating pain. Within the first 48 hours after injury, wrap ice in a towel and apply it to the affected area for 15-20 minutes per session, avoiding frostbite.

　　3. Heat compress: Applying a heat compress helps dilate local blood vessels, improve blood circulation, and accelerate the absorption of bruising and swelling. After the first 48 hours post-injury, apply a warm towel as a compress, extending the duration of each session as appropriate to aid recovery.

　　4. Elevate the affected limb: Elevating the injured hand helps reduce blood accumulation and promotes blood return, thus reducing swelling. While sleeping, place a blanket or pillow beneath the hand to keep it elevated above heart level.

　　5. Medication: Under a doctor's guidance, topical medications such as safflower oil, swelling and pain-relieving tincture, or musk analgesic plaster can be used to promote blood circulation, remove blood stasis, and relieve swelling and pain. Additionally, medications such as ibuprofen sustained-release tablets, diclofenac sodium tablets, or amoxicillin capsules may be taken as directed for pain relief, anti-inflammatory effects, and antibacterial action.

　　During treatment, it is important to adjust lifestyle habits and dietary patterns to promote recovery.
