I am adding this to my blog, because DVT (deep vein thrombosis) and PE (pulmonary embolism) are two more medical conditions that need prompt and even emergency treatment. It is important to know what symptoms to look for. The following is from Web MD.
Symptoms of deep vein thrombosis -- a blood clot in a deep vein -- may be difficult to identify. That's because deep vein thrombosis symptoms are similar to many other health problems.
If you're at risk for deep vein thrombosis (DVT), know your risks and stay alert to DVT symptoms. If you have symptoms, learn what you can do to confirm a diagnosis.
What Is Deep Vein Thrombosis?
Deep vein thrombosis is the formation of a blood clot in a deep vein, usually in a calf or thigh muscle. DVT can partly or completely block blood flow, causing chronic pain and swelling. It may damage valves in blood vessels, making it difficult for you to get around. A blood clot can also break free and travel through your blood to major organs, such as your lungs or heart. There, it can cause damage and even death within hours.
Signs and Symptoms of Deep Vein Thrombosis
Half of all DVT cases cause no symptoms. If you do have any of the DVT symptoms below -- especially if they occur suddenly -- call your doctor right away:
Swelling in one or both legs
Pain or tenderness in one or both legs, which may occur only while standing or walking
Warmth in the skin of the affected leg
Red or discolored skin in the affected leg
Visible surface veins
If a blood clot breaks free and travels to your lungs it's called a pulmonary embolism, and it can be fatal. Pulmonary embolism may not cause symptoms, but if you ever suffer sudden coughing, which may bring up blood; sharp chest pain; rapid breathing or shortness of breath; or severe lightheadedness, call 911 or go to an emergency room immediately.
Pulmonary embolism is the sudden blockage of a major blood vessel (artery) in the lung, usually by a blood clot. In most cases, the clots are small and are not deadly, but they can damage the lung. But if the clot is large and stops blood flow to the lung, it can be deadly. Quick treatment could save your life or reduce the risk of future problems.
What are the symptoms?
The most common symptoms are:
Sudden shortness of breath.
Sharp chest pain that is worse when you cough or take a deep breath.
A cough that brings up pink, foamy mucus.
Pulmonary embolism can also cause more general symptoms. For example, you may feel anxious or on edge, sweat a lot, feel lightheaded or faint, or have a fast heart rate or palpitations.
If you have symptoms like these, you need to see a doctor right away, especially if they are sudden and severe. Know your risk factors.
In most cases, pulmonary embolism is caused by a blood clot in the leg that breaks loose and travels to the lungs. A blood clot in a vein close to the skin is not likely to cause problems. But having blood clots in deep veins (deep vein thrombosis) can lead to pulmonary embolism.
Other things can block an artery, such as tumors, air bubbles, amniotic fluid, or fat that is released into the blood vessels when a bone is broken. But these are rare.
