I had surgery two months ago and on 4/8 developed a Pulmonary Embolism. I am now on two shots of Lovenox per day and 10mg of Warfarin. My INR is only at 1.9 after 3 weeks. I have recently developed pain in my left leg starting in the hip and radiating to the knee. Is this normal? Also, I have one hard lump in my stomach most likely at an injection site. Is this normal?
