When it comes to blood clots, most of the time it’s not something we think about. Most people believe blood clots are only a problem for the elderly and not something that should be worried about at a young age. However, this misconception couldn’t be further from the truth. A blood clot can affect anyone at any time regardless of age, however there are certain factors that contribute to someone being more prone to a blood clot.

Blood clots occur when blood cells begin to fuse together due to a lack of circulation. As these cells begin to collect, they transform from a liquid state to a more semi-solid consistency. This can be dangerous since the clot can begin to block blood flow. Even worse, if the blood clot breaks free it can lodge itself in the lungs or the heart, causing a pulmonary embolism which can be fatal if not treated quickly.

So who’s at risk for for a blood clot? Well, people with sedentary lifestyles are at a higher risk due to lack of movement. Even long trips in the car, when someone is sitting for more than four hours or more can be at risk for a clot. Of course, smoking and obesity can be contributing factors as well.

We did our research and found 15 signs/symptoms of blood clots that are important for you to be aware of. While not all of these symptoms indicate a clot, they are important to know nonetheless.

15. Leg Pain

One of the most common places for a blood clot to occur is in the lower leg. As the mass of blood cells transitions from liquid to a semi-solid state, it can begin to cause pain deep in the muscle where the vein is blocked. If you notice a consistent pain in your legs, you might want to have your doctor check it out.

14. Tenderness


With pain, also comes tenderness. Regardless of where a blood clot is located, it’s going to come with its own level of tenderness in the tissue surrounding it. This is due to the fact that the vein is blocked which is leading to poor circulation in the area of the clot.

13. Shortness of Breath


Shortness of breath is a symptom of a blood clot that has been dislodged from somewhere else in the body and has become trapped in the lungs. This is also known as a pulmonary embolism. If not treated right away, it can lead to death depending on the severity of the clot.

12. Chest Pain


Chest pain is not always a symptom of a blood clot, however if a blood clot becomes trapped in the lungs or in the heart, it can trigger severe pain paired with shortness of breath. If you notice that you’re having chest pains for significant lengths of time, contact your doctor immediately.

11. Red Streaks

One of the first signs of a blood clot besides pain and tenderness can be a red “streaking” effect where the clot is located. As the circulation in the area begins to breakdown, redness in the surrounding tissue can begin to occur. These red streaks can also be hot to the touch as well.

10. Swelling

One of the most common signs of a blood clot in the leg is swelling. As circulation begins to breakdown in the limbs, fluid begins to be retained in the tissue. You can tell if you are experiencing fluid retention by pressing down on your leg (or any other limb) and the pressure creates an indent that doesn’t go away immediately.

9. Vein Clusters

Smaller blood clots can create vein clusters, also know as varicose veins. These veins are larger, purple and usually look like a tangles mass on the surface of the skin. While not always indicative of a blood clot, they can sometimes be a symptom.

8. Heart Palpitations

Heart palpitations are usually a sign of a blood clot within or around the heart. As the clot begins to disrupt the blood flow, your heart begins to work even harder, which can result in an erratic heart beat or palpitations.

7. Soreness in Limbs

Most soreness triggered by a blood clot manifests itself as a dull ache that’s persistent and doesn’t ever go away. As the blood clot grows or continues untreated, this dull ache can transform into extreme acute pain in the area that the clot has lodged itself.

6. Intense Sweating

Extreme sweating, usually during the night, is a prominent symptom of a pulmonary embolism, which is a direct result of a blood clot that has moved through the body and become lodged in the lung. If you notice you’re experiencing night sweats regularly, consult your doctor to determine the cause.

5. Unexplained Cough


If you develop an unexplained cough that is persistent and does not go away, it’s possible you’ve developed a blood clot in your lungs. As this progresses, one may start to cough up blood which is a sign that the clot has triggered a pulmonary embolism.

4. Dizziness

One symptom of a blood clot in the brain is dizziness. This can result in being unable to focus or drive. Vertigo can last for days, not just hours. If you’re experience symptoms such as these we recommend getting to a hospital immediately.

3. Headache


While headaches can be triggered by a multitude of things, a persistent headache that lasts indefinitely could be a sign of a blood clot in the brain. If left untreated, the brain could begin to be deprived of oxygen as circulation slows. It’s important to remain vigilant and aware of your body in order to avoid a more serious situation.

2. Nausea

Sometimes blood clots can form in the veins that drain the blood from your intestines. This is usually caused by diseases of the liver or diverticulitis. If you have a blood clot in the abdominal area, nausea and vomiting are commonly displayed symptoms.

1. Blood in Urine

Blood clots forming in the kidneys are usually identified through blood in the urine. As the clot lodges itself in the kidney, it prevents the kidneys from removing waste from the body. This can result in high blood pressure and in worst case scenarios, kidney failure.
