Hello and welcome to HCM,
Swelling and pain in the ankle/ heel region with ahistory of DVT suggests that these symptoms are most probably due to DVT itself.Coumadin
therapy will dissolve the deep vein thrombus
and/ or pulmonary emboli
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
Dr Shailja P Wahal
