<s>[INST] I was diagnosed with DVT & PE 2 weeks ago. After 9 days of Coumadin therapy I have swelling & soreness of the ankle/heel area. X-rays confirmed soft tissue swelling. Why has this happened & howllong should I expect this foot pain? I have been using a cane but today started using a walker. Thanks in advance for your reply. [/INST] Hello and welcome to Chat Doctor, Swelling and pain in the ankle/ heel region with history of DVT suggests that these symptoms are most probably due to DVT itself. Coumadin therapy will dissolve the deep vein thrombus and/ or pulmonary embolic if present. Pain can be relived by analgesics. However, a Doppler study of the lower limb veins is necessary to know the status of the veins, whether there is presence of any thrombus or not. Besides since you are on anticoagulant therapy, INR value should be followed up strictly. Thanks and take care Chat Doctor.  </s>
