On July 8th 2015 i was admitted to the hospital coughing up blood the next day they ran a scan on my lungs and i had a large clot in both lungs and some small ones they started me on heparin drip and the next day on warfarin i was released a week later and now im on oxygen. But my question is i have been having burning in my chest today, is this normal after pe ? My doctor only wants me to come back every 3 months for inr check. I have severe anxiety and feel depressed most days..
