A deep vein thrombosis (DVT) is a blood clot that has formed in one of the large veins of your body, usually in your legs. According to the Mayo Clinic, a DVT can develop during times of inactivity, such as sitting for prolonged periods of time. In addition, medical conditions that increase your risk for blood clots can also increase your risk of developing a DVT. A DVT is a serious medical condition because a blood clot can migrate from a large vein to your lungs. While symptoms can help diagnose a DVT, these warning sign only occur in one half of cases, according to the Mayo Clinic. However, if you are experiencing symptoms of a DVT, seek immediate medical treatment.
Swelling
The Mayo Clinic states that swelling can occur in the leg, arms or neck with a DVT. This occurs because a blood clot is blocking a vein, which causes a backup in blood going to the heart. Because of this backup, fluid moves from the vein into the surrounding tissues in your extremities causing swelling. If you are experiencing a swollen leg, seek proper diagnosis and treatment from your doctor because you may have a DVT.
Pain
Pain is also a common symptom of a DVT. The Mayo Clinic states that this pain can be localized in your ankle and foot and feels like a cramp or a "charley horse." Leg cramping is never normal and may be a sign of a DVT or another underlying disease. Also, be aware of pain in your arms or neck, as this is a symptom of an upper extremity DVT. Alert your doctor if you are experiencing this symptom.
Redness and Warmth
According to the Mayo Clinic, redness and warmth can occur over the area affected by a DVT. Seek medical treatment if your skin is red and warm, as this may be a DVT or another medical condition.
When to Seek Emergency Treatment
The most dangerous complication of a DVT is the movement of a large vein blood clot to the lungs, also called a pulmonary embolism. According to the National Heart, Lung and Blood Institute, warning signs of a pulmonary embolism include unexplained shortness of breath, problems breathing, chest pain, coughing, coughing up blood and an irregular heartbeat. Call 911 immediately and seek immediate medical attention if you are experiencing any of these symptoms.
