What should I do if my finger is bruised and swollen due to pressure?

　　Finger bruises with hematoma can usually be treated with methods such as ice compresses, warm compresses, avoiding strenuous activity, elevating the affected limb, and medication to promote hematoma absorption and accelerate recovery. If abnormalities occur, prompt medical attention is recommended. Detailed explanations are as follows:

　　1. Ice compress: Within 24 hours after the injury, apply an ice pack or wrap ice in a towel and place it on the affected area as soon as possible. Ice compresses help reduce exudation, prevent worsening of the bruise, and alleviate pain and swelling.

　　2. Warm compress: After 24 hours, switch to warm compresses. Applying a warm towel or hot water bag to the affected area can help improve blood circulation and promote absorption of the bruise.

　　3. Avoid strenuous activity: During the recovery period, avoid strenuous activity or excessive movement of the injured finger. Rest appropriately to allow sufficient time for recovery.

　　4. Elevate the affected limb: Elevate the injured finger above heart level to reduce congestion and swelling. Keeping the finger elevated aids in the absorption and resolution of the bruise.

　　5. Medication: If the bruising and swelling are severe, blood-activating and stasis-resolving medications such as Sanqi tablets, Angelica tablets, or anti-inflammatory analgesic plasters may be used under a doctor's guidance.

　　Before the bruise has subsided, excessive finger movement should be avoided to prevent worsening of the bruising and pain. If the bruising continues to worsen or abnormal symptoms such as restricted finger movement or numbness occur, prompt medical evaluation and treatment are advised.
