6 Subtle Signs of Blood Clots Everyone Should Be Aware Of



Blood clots typically occur after an injury as a protective reaction of your body to avoid losing too much blood. However, clots can also occur in an artery or vein even if there is no obvious injury. And if it doesn’t dissolve on its own or you don’t get timely treatment, it can result in life-threatening complications. 

A blood clot can provoke various signs and symptoms depending on where it’s located—in the heart, brain, arm, leg, lung, or abdomen. Some of the signs can occur in many other conditions, so it’s a good idea to speak with your physician or visit a vein clinic to get the proper diagnosis. Plus, it’s not uncommon for blood clots to be symptomless. Let’s look at some silent signs and symptoms of blood clots you need to watch out for.

1. Back pain 

Back pain doesn’t sound like a blood clot symptom, however, it could indicate that a blood clot is located in the pelvic area or in the inferior vena cava, which is the major abdominal vein. The American College of Cardiology reports that 2.6 to 4 percent of people with deep vein thrombosis also have inferior vena cava thrombosis. 

Though back pain due to a blood clot is one of the more rare symptoms, these types of clots can lead to permanent damage if left untreated, since they block blood flow to the extremities. 

If you have back pain along with other blood clot symptoms, consult your healthcare provider. Though blood clots can provoke back pain, the most common reasons for lower back pain aren’t usually blood clots.

2. Skin warmth 

A variation in skin temperature where the clot is located is a common sign of blood clots. It’s provoked by a disruption of blood flow. If you have persistent temperature variation and you also have a history of a high risk of blood clots, consult your doctor as soon as possible. 

3. Dyspnea (shortness of breath)

Shortness of breath is often associated with a pulmonary embolism. A pulmonary embolism is when a blood clot blocks a vessel in the lung. Other common symptoms of pulmonary embolism include difficulty breathing and chest pain.

Back pain is another lesser-known symptom of a blood clot in the lungs. Sometimes, people with a pulmonary embolism might experience a drop in blood pressure and pass out, or they might even cough up blood.

These symptoms are considered a medical emergency, however, any clot symptoms should be taken seriously and checked by your healthcare provider. In addition to prolonged sitting, other risk factors for deep vein thrombosis include injuries, like fractures and major surgery, chronic health problems, such as heart and lung disease, pregnancy, and hormone use, such as birth control pills.

4. Skin discoloration 

Skin discoloration occurs when a blood clot affects normal blood flow. If an area of one leg has become red or has a different color in any way, a blood clot could be to blame. This sign should be checked by your doctor.

5. Leg cramps

Those who have had a blood clot in the leg report that they’ve experienced cramps or pain similar to a charley horse. A blood clot that occurs in a major vein can contribute to leg aches, pain, and cramping. Clots can develop slowly or occur suddenly, especially after a prolonged time in a sitting or cramped position, like on a long-distance flight.

6. Swelling 

According to the Centers for Disease Control and Prevention (CDC), swelling in the arm, hand, foot, ankle, or leg is one of the most common symptoms of a blood clot. Blood clots are only one of the reasons why a body part might suddenly get swollen.
