Blood Clots

Blood Clots

People often confuse the term blood clot with blood blisters but they are in fact two different things. However a blood clot can cause a blister to form over the area where your blood is clotting. Your blood is the liquid flowing in your blood vessels, which moves at a constant motion from your heart through your arteries and various places throughout your body. When there is an interaction between the blood flowing through your body and the blood vessel walls, it causes a clot, which is a semi-solid mass of blood.


There are good and bad blood clots. Good blood clots have a medical purpose which is to stop the bleeding following an injury, while what are considered bad blood clots are formed from other areas of damage. An example of a bad blood clot would be one in which it occurs in an artery in the brain or heart. When the blood flowing is exposed to certain substances, it can cause a clot. These substances are called thrombogenic as they cause a formation, which is the blood clot. These substances may be in the blood vessel walls or in the person’s skin.

Risk Factors

There are many different risk factors that can lead to an increased risk of blood clotting which may be dangerous depending on the circumstances. Some medical conditions and diseases may actually cause a narrowing of blood vessels which results in clotting such as high blood pressure, high cholesterol, smoking, diabetes, and a family history of blood clotting disorders. Venous thrombosis clots, which are blood clots occurring in the vein, usually happen from immobility such as during a long car ride, someone who is bedridden after an injury or Illness or someone with an orthopedic injury causing them to be immobile.


It can often be difficult to determine when you have a blood clot, but each type of clot will give you certain signs and symptoms. With a venous clot, symptoms include swelling, redness, warmth and pain in the area where the blood clot exists. Arterial blood clots (existing in your arteries) can also cause some symptoms such as pan in that area of your body not getting proper blood supply, numbness, weakness or complete paralysis, whiteness of the limb where the clot exists and possible swelling.

Venous Blood Clots

Venous blood clots exist in the vein and usually happen more slowly. This is why they lead to pain and swelling. Venous blood clots are often diagnosed by how much the symptoms worsen. With a venous blood clot, the extremity shows swelling and redness along with warm and pain which is how doctors typically begin diagnosing this type of clot.

Arterial Blood Clots

Arterial blood clots on the other hand exist in the arteries and the associated symptoms happen immediately. This is because the body’s tissues need oxygen immediately which is restricted with the loss of blood supply from a clot. An Arterial blood clot shows more dramatic symptoms which is what lead doctors to diagnosing this type of clot, such as an arm or leg being cool to the touch, stark white and numb.
