Taking Brufen (Ibuprofen 400 mg) twice daily can help reduce swelling and pain because it is a nonsteroidal anti-inflammatory drug (NSAID) that works by decreasing inflammation.

However, since your finger injury happened 10 days ago and the pain started after 8 days, it is important to monitor for signs of infection or other complications. If the swelling and pain persist or worsen, or if you notice redness, warmth, pus, or fever, you should see a doctor promptly.

In the meantime:

• Continue taking the medication as prescribed.
• Rest and elevate your finger to reduce swelling.
• Apply ice packs intermittently if it helps.

If symptoms do not improve or worsen, a doctor may need to examine your finger to rule out fractures, infections, or other issues that might require additional treatment such as antibiotics or immobilization.

Always follow your doctor's advice and do not hesitate to seek medical attention if you have concerns about your injury or medication effectiveness.To narrow down potential causes, we will need some more information.I understand you have swelling on your index finger and it's hurting.
