My mother in law had diagnosed with PE and she is in blood thinner medication. Using Pradaxa since diagnosed . Recently after two months blood came yesterday while coughing four times with in half an hour and then it stopped. Cough is not going about four months now . We have done CT scan one month back and been told us thrombus is still present in left main pulmonary artery and it will get cure over a time . Please let us know is it common coughing up blood (hemoptysis) with PE are do we need to undergo any further diagnosis please suggest
