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 agree with RMB that it would be highly unusual that there is another dvt developing. You need to look for those signs.....is my leg swollen? Is there noticeable pain in the calf or thigh? In the case of a dvt that has gone ignored or unnoticed for too long then your walking might be hindered. Look for those signs.
I would certainly consult with your doctor should you be concerned but per my experience it was normal.
Thanks,
