Prolonged Immobility. Sitting or lying down for long periods—due to prolonged bed rest after illness or a long airplane flight, for example—can cause blood to pool in the legs, leading to deep vein thrombosis (DVT) and, worst-case scenario, pulmonary embolism if the clot travels to the lungs.
Symptoms of Pulmonary Embolism (PE), or Blood Clot in the Lung: Shortness of breath. Chest pain or discomfort, especially if it worsens when you take a deep breath, cough or lie down.
lie on their sides with a pillow between the knees if desirable.
Bed rest creates physical risks as well. The limited physical activity with bed rest can lead to muscle atrophy, bone loss, weight fluctuations, and blood clots or DVT (deep vein thrombosis).
DON'T stand or sit in one spot for a long time. DON'T wear clothing that restricts blood flow in your legs. DON'T smoke. DON'T participate in contact sports when taking blood thinners because you're at risk of bleeding from trauma.
It takes about 3 to 6 months for a blood clot to go away. During this time, there are things you can do to relieve symptoms. Elevate your leg to reduce swelling. Talk to your doctor about using compression stockings.
Following a DVT, your leg may be swollen, tender, red, or hot to the touch. These symptoms should improve over time, and exercise often helps. Walking and exercise are safe to do, but be sure to listen to your body to avoid overexertion.
Sitting for a long time without getting up and walking around can cause blood to pool in the veins of your legs. This can lead to blood clots.
The skin around painful areas or in the arm or leg with the DVT may feel warmer than other skin. Trouble breathing. If this happens, it could mean that the clot has moved from your arm or leg to your lungs.
Once DVT or VTE is treated, doctors recommend that patients be sure to stay active. “You want people to exercise, because the lack of exercise causes clots,” says Ellen Hillegass, a physical therapist with American Physical Therapy Association board certification in cardiovascular and pulmonary clinical specialty.
Massage is also contraindicated if the person has a blood clot. Another word for this is “deep vein thrombosis.” The risk is that the massage may cause the blood clot to dislodge and travel to the lungs, thus causing a pulmonary embolism that could be life-threatening.
Do not sit so that you put steady pressure on the back of your knee. Prop up your legs on a stool or chair if your legs swell when you sit.
As the clot gets worse, you may feel a sensation ranging from a dull ache to intense pain. The pain may throb in your leg, belly, or even arm. Swelling in the spot where the blood clot has formed or throughout your entire arm or leg. Change in color.
Elevate your legs above the level of your heart.
Elevate your legs when you sit or lie down, as often as you can. This will help decrease swelling and pain. Prop your legs on pillows or blankets to keep them elevated comfortably.
Staying active and moving around may help prevent blood clots.
Sitting still for 4 or more hours slows down the blood flow in your legs. This makes your blood more likely to clot. And for the next few weeks, your blood clot risk stays higher than normal.
Sick Leave and Disability
In most DVT cases, blood thinners are enough to stop new clots from forming or traveling while your body gets rids of the existing clot. But severe clots may need more complex treatments or even surgery. In this case, you might need more time off from work.
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.
Elevation: Elevating the legs can help to instantly relieve pain. A doctor may also instruct a patient to elevate the legs above the heart three or four time a day for about 15 minutes at a time. This can help to reduce swelling.
Full blood thinning effect is achieved within 2–3 h. Therefore, there is no need for the initial injections with an additional blood thinner. After being stopped, warfarin takes 5–7 days to clear the body. Takes 24 to 48 h to clear after being stopped.
Stay Hydrated
Dehydration contributes to the development of sluggish blood flow and blood clots. NYU Langone doctors advise drinking 8 to 10 8-ounce glasses of water each day for optimal blood flow. It's especially important to do this when your mobility is limited for long periods, such as while traveling.
1) Constriction of the blood vessel. 2) Formation of a temporary “platelet plug." 3) Activation of the coagulation cascade.
