Pulmonary Embolism Support Group
By far the most common form of pulmonary embolism is a thromboembolism, which occurs when a blood clot, generally a venous thrombus, becomes dislodged from its site of formation and embolizes to the arterial blood supply of one of the lungs. Symptoms may include difficulty breathing, pain during breathing, and more rarely circulatory instability and death.
I was told that if it was just a speck or two it wasn't a big deal, but anything like a teaspoon or bigger might warrant a call or visit to the Dr.
It is probably nothing to worry about though - often a coughing fit can just pop a blood vessel. Had you not had the PE, you would probably never have noticed it.
Tim you are right, I probably would not have noticed it pre PE.
I was coughing up blood for 6 weeks after my pe, somedays a lot more than others. I was terrified!! But I took samples to a doctor as disgusting as it sounds and he said it was either from the inflammation in my lungs or from a chest infection I had at the time. Any inflammation can cause it but as you were in a coughing fit it is most likely down to a burst capillary which are also more sensitive when on warfarin. I was told if you cough up more than a few tea spoons, then be concerned. If you fill a tea spoon with water and pour it out on the side you will see it is actually quite a lot. Nevertheless if it persists and worries you go get checked.
But if it were me, I'd call my doc. Probably nothing, but I'd want his take.
