[56F] With painful, itchy, swollen left index finger

What might be happening

Based on the information you've provided, the most likely cause of your symptoms is a bacterial infection, possibly cellulitis. Cellulitis is a common bacterial skin infection that can cause redness, swelling, pain, and warmth in the affected area. The slit in your finger could have allowed bacteria to enter your skin and cause the infection.

• Treatment usually involves antibiotics to kill the bacteria causing the infection. Pain relief and anti-itch medications may also be prescribed to help manage your symptoms.

What you can do

While I strongly recommend you seek medical attention as soon as possible, here are some things you can do in the meantime:

1. Keep the area clean and dry: Wash the area gently with soap and water, then pat it dry. Avoid scratching or picking at the area to prevent the infection from spreading.

2. Apply a cold compress: This can help reduce swelling and relieve pain. Wrap a bag of ice or a cold pack in a cloth and apply it to the area for 15-20 minutes at a time.

3. Elevate the affected hand: This can help reduce swelling. Try to keep your hand elevated above the level of your heart as much as possible.

4. Over-the-counter pain relievers: Non-prescription pain relievers like ibuprofen can help manage your pain.

What you should look out for

Please seek immediate medical attention if:

• The redness, swelling, or pain gets worse
• You develop a fever or chills
• You notice red streaks spreading from the infected area
• You have difficulty moving your finger
