A blood clot, also known as a thrombus, is a clump of blood that forms when blood thickens and clumps together. Blood clots can occur in the veins or arteries and can be dangerous if they form in certain areas of the body such as the legs, lungs, or brain. Here are some signs and symptoms of a blood clot:
- Swelling, warmth, redness, or pain in the leg, ankle or arm.
- Tenderness or cramping in the leg or arm.
- Skin that feels hot to the touch.
- Leg or arm that is red or discolored.
- Shortness of breath, chest pain, or rapid breathing
- Coughing or wheezing
- Rapid or irregular heartbeat
- Headache, vision problems, or confusion
- Nausea, vomiting or lightheadedness
If you suspect that you have a blood clot, it is important to seek medical attention as soon as possible. Blood clots can be life-threatening if they travel to the lungs, brain or heart. If you have any of the above symptoms or if you have risk factors for blood clots such as a family history, recent surgery, pregnancy or a history of blood clots, you should see a doctor immediately.
