Duplex ultrasonography is an imaging test that uses sound waves to look at the flow of blood in the veins. It can detect blockages or blood clots in the deep veins. It is the standard imaging test to diagnose DVT. A D-dimer blood test measures a substance in the blood that is released when a clot breaks up.
throbbing or cramping pain, swelling, redness and warmth in a leg or arm. sudden breathlessness, sharp chest pain (may be worse when you breathe in) and a cough or coughing up blood.
Typically, your provider will ask about your current symptoms, family medical history and risk factors for clots. They will examine your extremities (arms and legs) for swelling and look for tenderness and skin discoloration. If your provider suspects a clot, they may do certain blood tests or imaging tests.
An ultrasound is the most common diagnostic test for DVT and uses sound waves to create a picture of the arteries and veins in the leg. Doctors also can order a blood test known as the D-dimer test. Computed tomography (CT) scans are typically used to diagnose PE.
They include sudden shortness of breath, chest pain while breathing in or coughing, rapid breathing, rapid pulse, feeling faint or fainting, and coughing up blood. Postphlebitic syndrome. Damage to the veins from the blood clot reduces blood flow in the affected areas.
Signs that you may have a blood clot
leg pain or discomfort that may feel like a pulled muscle, tightness, cramping or soreness. swelling in the affected leg. redness or discoloration of the sore spot. the affected area feeling warm to the touch.
Blood clots usually dissolve on their own. If not, the clots can potentially lead to life-threatening situations. There are two main types of blood clots: thrombus (clot does not move) and embolus (clot breaks loose and moves). If the clot is immobile, it generally won't harm you.
Small blood clots in the calf can sometimes go undetected for several days or weeks, especially if they don't show any symptoms. If left untreated, however, DVT can travel up the veins in the leg to the lungs or other major organs in the body, leading to a potentially fatal pulmonary embolism or similar complication.
“But about 30–40% of cases go unnoticed, since they don't have typical symptoms.” In fact, some people don't realize they have a deep vein clot until it causes a more serious condition. Deep vein clots—especially those in the thigh—can break off and travel through the bloodstream.
About 25% of people who have a PE will die suddenly, and that will be the only symptom. About 23% of people with PE will die within 3 months of diagnosis, just over 30% will die after 6 months, and there is a 37% mortality (death) rate at 1 year after being diagnosed.
If you think you have a blood clot, call your doctor or go to the emergency room right away! Blood clots can be dangerous. Blood clots that form in the veins in your legs, arms, and groin can break loose and move to other parts of your body, including your lungs.
Blood clots can cause a heart attack, stroke and death. If you are experiencing the symptoms of blood clots, you should go to the nearest ER immediately.

This evaluation, known as Homan's Test, consists of laying flat on your back and extending the knee in the suspected leg. Have a friend or family member raise the extended leg to 10 degrees, then have them squeeze the calf. If there's deep pain in the calf, it may be indicative of DVT.
A large clot can cause the lungs to collapse, resulting in heart failure, which can be fatal. About one in 10 people with an untreated DVT develops a severe pulmonary embolism.
A deep vein thrombosis (DVT) is a blood clot that occurs in a deep vein, usually in the lower leg, thigh, pelvis, or arm. A DVT can occur without any symptoms, but it is often accompanied by swelling, pain, and redness of the skin.
Yes—The cramping sensations and pain that occur with DVT will persist and even worsen with time. Stretching or “walking it off” like an ordinary charley horse will not ease DVT pain or clear it up.
Does blood clot pain come and go? Unlike the pain from a charley horse that usually goes away after stretching or with rest, the pain from a blood clot does not go away and usually gets worse with time.
Massage stimulates blood circulation, therefore can dislodge a clot, even if the point of massage is elsewhere on the body.
Pain in one leg or arm and not the other is a warning sign of DVT. Discomfort often increases with walking or standing for an extended period. Many people mistake this feeling for a pulled muscle, but leg pain from DVT will not go away with time as a muscle injury does.
Make an appointment with your health care provider if:
You have pain during or after walking. You have swelling in both legs. Your pain gets worse. Your symptoms don't get better after a few days of treating them at home.
Varicose Veins
When they don't work right, blood pools inside your veins. They swell and become large and rope-like. That's another difference from DVT -- the surface-level clots that come with varicose veins are uncommon and don't usually break free and travel to your lungs.
