Blood clot: Four tell-tale signs of a dangerous clot developing in your leg


It is important to recognise the early warning signs of a blood clot, which is essentially an area of thickened blood that has formed a semi-solid mass inside of a vein. A blood clot that forms in the leg leads to swelling, tenderness, redness and a warm feeling around the area of the clot, Healthdirect stated. Book an appointment as soon as possible if you suspect you have a blood clot.

You are likely to be referred for a CT or ultrasound if your doctor also suspects you have a blood clot.

In addition, you might be required to have a blood test to check for signs that your blood is clotting more than it should.

Most commonly, blood clots found in the leg can be treated by taking blood-thinning medication, such as warfarin.

This will help prevent the clot from growing bigger, and it will also help to prevent new clots from forming.

  • You are overweight
  • You are pregnant
