Deep vein thrombosis is a blood clot in the leg
It normally causes severe swelling and severe pain somtimes no symptoms at all
if you think you have dvt seek medical attention as the clot can break of from your leg and travel to your heart and cause cardiac arrest Or Heart Attack.
Unlikely but can
Also You If It Breaks Of Into The Lund This Is Calles Pulmonary Embolism ....A Clot That Travels To The Lung This Is Aswell Life-Threatening And Needls To Be Treated Quickly Symptoms Are pain in rib when you breathe coughing blood
a clot in the leg is very very rare
hope this helped you
