How To Recognize A Blood Clot: 6 Tell-Tale Symptoms

Date July 20, 2018

Some forms of blood clots, like bruises and cuts, are nothing to worry about. If you have a cut, your blood starts to coagulate and forms a scab to prevent blood loss. But blood clots inside your body are called thrombosis and can be fatal. Thrombosis often acts as the main cause of the appearance of varicose veins.

Below is a checklist of six symptoms that are signs of thrombosis and require urgent medical attention.

Swelling in one of your limbs

It may be a sign of decreased blood flow to the limb caused by deep vein thrombosis. This is dangerous, because blood clots prevent normal blood flow to your organs which deprives them of oxygen.

Leg or arm pain

If you experience pain in one of your extremities that feels like a cramp, and the area is tender and warm to the touch, it may be a sign of a blood clot.

Red streaks on your skin

Bruises are also a form of a blood clot, but usual bruises don’t have those. If you see red streaks along your veins, and the area feels warm to the touch, you need immediate medical attention.
