I.am female, 54, 5'4". 285# I fell in my office app one week ago incurring a massive bruise on the side & back of my right leg, from my knee down. I am on Coumadin & my INR was 3.3 & my coumadin dosage was tweaked. I then went on a road trip, & have spent the past 2 days driving. My rt leg, in the midst of the healing bruise, now has a large red, warm, tender area. Cellulitis? DVT?
