###Human: Why is the pulmonary embolism patient having burning sensation in legs? ###Assistant: Hello. DVT (deep venous thrombosis) that is a blood clot in the legs does not cause burning sensation but causes swelling of the affected leg and you are already on blood thinners. I hope you INR (international normalized ratio) is within therapeutic range unless you are taking new oral anticoagulants. I think you should do blood sugar and preferably HbA1c (glycated hemoglobin) and relax as it cannot be DVT. For more information consult a cardiothoracic surgeon online -->
