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 had light-headedness shortly after my PEs, but it was because of orthostatic hypotension (BP falling too low) than anything else. I've had several echos also with no issues found at all. I'll have another one next year just to make sure. In the meantime, I try really hard to stay hydrated and take daily Vit C, potassium, magnesium, and calcium to keep the minerals my body needs.
Just as an FYI, you can still get pregnant, if that is important to you. You'd have to do Lovenox injections throughout, but it is totally do-able.
Hang in there!
