Blood clots, or deep vein thrombosis, occur when a blood clot forms in a vein. Most blood clots develop in the legs or arms. They can be very dangerous, particularly if they travel through the veins to the lung or heart. Proper identification and prompt treatment of a blood clot are vital to quick recovery. Common symptoms that may indicate you have a blood clot include swelling in only one arm or leg, pain, and tenderness that may be mistaken for a cramp until it doesn’t go away. Some people with blood clots also notice the affected area is warm to the touch and slightly discolored. Pain or cramping that does not resolve in only one leg is usually a solid indicator of a blood clot, and if you notice multiple symptoms of a blood clot occurring at once, seek medical assistance right away. If, in addition to the above symptoms, you are suddenly short of breath, experience chest pain, begin to cough with no explanation, start to sweat, or become dizzy, call 911 right away.
