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.
Based on what my doctor told me - and the posts on this support site (and thank goodness for this support site!) - it seems like recovery from PEs varies from person to person. In my case, while I returned to work two weeks after my DVT with bi-lateral PE, I still don't feel 100%, and I get winded very easily - especially if it is cold outside (I don't really know why).
A friend of mine who had the same thing happen to her didn't return to work for six weeks, and she said she didn't feel like her lungs returned to normal function until six months after everything happened.
I think it's great you are exercising! Keep up the great work.
