Signs You May Have a Blood Clot in Your Leg


Blood clots may not sound life threatening; however, they can cause death if left untreated. Blood clots which develop inside deep veins in the legs can detach and travel to the lungs causing PE (pulmonary embolism). This usually happens when the clots are untreated and can’t dissolve on their own.

Blood clots in the legs form due to prolonged periods of travel or instances where you remain immobile for a long time in cramped spaces such as in a bus, train or an airplane with little to no opportunities to walk around or stretch your legs.

Other causes of blood clots according to the U.S. Agency for Healthcare Research & Quality include; having heart problems, vein problems (bad veins or varicose veins) and injury, i.e., having a broken leg, hip or pelvic bone. Blood clots have also been linked to genetic causes. You are at risk of getting a blood clot in your leg or other areas if a member of your family has had the same problem in the past or currently.

Your risks of developing a blood clot are also higher if you have had a clot before, if you are paralyzed or have a stroke, if you are obese, have cancer, or you are being treated for cancer. Older people (aged 65 and above) also have a higher risk. Some medication and hormones can also increase your risks, i.e., hormones taken for birth control. A bruise or bad bump, as well as a specific injection spot, can also trigger the formation of a clot. Although blood clots can affect anyone, you are at a higher risk if you lead an unhealthy lifestyle i.e., you don’t exercise, eat healthy or have enough rest.
