3. Swelling in the legs
With the associated pain, throbbing, or cramping that comes with a potential case of DVT, you might also experience swelling or redness in the affected body part. The swelling occurs because of the lack of proper blood flow due to the blood clot blocking off the flow of blood through the blood-stream. Swelling and hotness in the legs can be treated with the application of heat pads, which improve the overall blood flow to the legs – and they’re generally recommended for DVT aftercare.
Most often, a simple ultrasound examination is enough to spot a blood clot in the body – and luckily it’s one of the least invasive procedures. If that doesn’t do it, the dye is injected into the affected veins and a scan (called venography) is then done to catch the potential clot. Blood clots can also be seen through an MRI (Magnetic Resonance Imaging) if further testing is necessary.
