[54F] Sudden onset of finger swelling and discoloration

What might be happening

Based on the symptoms you've described, here are a few possibilities:

• Phlebitis: This is inflammation of a vein, often in the leg, but it can also occur in the arms. Symptoms can include swelling, redness, warmth, and pain. The affected vein can sometimes be seen as a red, hard, tender cord.

  • Treatment typically involves applying a warm compress to the area and taking over-the-counter anti-inflammatory medications to reduce swelling and pain.

• Thrombophlebitis: This is a blood clot in a vein which causes inflammation and pain. The clot can be superficial (just under the skin) or deep (deep vein thrombosis). The symptoms you've described could be consistent with a superficial clot.

  • Treatment usually involves blood thinners to dissolve the clot, compression stockings to reduce swelling, and possibly surgery in severe cases.

• Cellulitis: This is a bacterial skin infection that can cause swelling, redness, and pain. The skin may also feel warm to the touch.

  • Treatment typically involves antibiotics to kill the bacteria.

• Raynaud's disease: This is a condition that causes some areas of your body — such as your fingers — to feel numb and cool in response to cold temperatures or stress. It can also cause fingers to change color (white, then blue, then red) as they warm up.

  • Treatment usually involves avoiding triggers (like cold), and medications to improve blood flow.

What you can do

Given the symptoms you've described, it's important to seek immediate medical attention. While waiting for medical help:

1. Try to elevate your hand above the level of your heart to reduce swelling.
2. Apply a warm compress to the area to increase blood flow and reduce pain.
3. Avoid any strenuous activity with the affected hand.

What you should look out for

If you experience any of the following symptoms, seek immediate medical attention:

• Severe pain
• Rapid spread of swelling or discoloration
• Difficulty moving your fingers or hand
• Signs of infection such as red streaks leading from the area, pus, or a fever
