Hi doctor, My pain started behind knee, but now is causing recurrent chest pains and shortness of breath. I could not do much physical activity. There is no previous history of such event. I am currently on Aspirin. I had an EKG, lung x-ray and D-dimer blood test. Is it possible to have a pulmonary embolism with negative D-dimer test? If the clot breaks or moving, then will D-dimer work? What else could cause pulmonary embolism like symptoms?
