[|Human|] I have a raised, lump area on inside of my right calf. No redness or bruising. No pain in particular but I know it is there. I am 56, female with history of DVT/PE. I am on Coumadin and my last check I was 1.7. I take 2mg 6 days a week. I just noticed the swelling yesterday.
[|AI|]  Hi. Thanks for your query and a correct history leading to a diagnosis. Since you are on Coumadin the most probable cause of such a lump which appeared yesterday and is large enough to be seen on the inside of the calf is most probably a hematoma unless proved otherwise. I would advise you to go for high resolution ultrasonography and color Doppler to get a confirmation. Get the coagulation profile tested, you may need to stop Coumadin under your Doctors supervision. You may not need major treatment unless the tight bandage does not help]
