question: Came out of the hospital a month ago with multiple clots in my lungs and one in the back of my left leg. Took shots of loveonx and on warafin. INR checks good between 2-3. The question I had was that every now and then I feel a mild discomfort above my heart area in my chest. When I take a deep breath I can feel the same discomfort in the same area. Is this caused by the clots? They told me I have some in my pulmenary artiries.
