I have two hematomas on the back of my left hand as a result of a minor injury experienced a week ago. There was immediate swelling of blood in the location of the injury which spread to cover all of the back of my hand. At that time I went to the emergency room where I was x-rayed. Then a compression bandage was put over the area and ice was applied. Now the overall swelling has gone down but my fingers are turning black as well as a black area down my wrist. The hematomas are not looking any bigger but do hurt if bumped. I am on warfarin...4.5 mg per day and have been on this for about 4 years. Otherwise, I am in good health. Should I be concerned, seek a physician (which I did on Tuesday following the injury), or is there something else I can do? I try to keep it elevated and protected.
