  • There is swelling in the affected areas. If the trauma was serious, you should check to see that there was no damage to the delicate bones below the clot
  • The skin around the blood clot is discolored; it starts off as being red, then turns purple and finally black.
  • The finger will feel tender to the touch
  • There will also be pain when you touch something hot, such as your cup of hot chocolate in the morning or when you are cooking some food


The reason that the blood clot formed in the first place may not be alarming. The clot can form due to an incident that you never even paid attention to. However, some of the causes should not be taken for granted. Here are some of the causes of getting a blood clot in the finger:

  • Injury or trauma – this would be events such as pinching, or when a door is slammed on the finger.
  • Damage to the blood vessels by other activities. This is very common in people who use their hands when playing sports. Basketball players, baseball players, handball players and volleyball players come across this kind of injury several times within a single season.
  • Immobilization – this is very common in people who have just come from surgery and do not move around a lot. The blood does not move as it should and a clot will form.
  • Rupturing of a piece of cholesterol plaque in the finger’s blood vessels – this will normally cause bleeding in the tissues and this will form the blood clot.

It should be noted that when a blood clot in the finger completely blocks a blood vessel, it will affect the circulation of the blood. The finger will then swell a lot and turn red, then purple and finally black. This is a dangerous situation and should get immediate medical attention.
