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.
As long as your INR is in range, I would take it easy for a couple days and see how you're doing next week.
Of course, if you're really worried that you have a new problem, just go to the ER.
The one nice thing about a DVT is it requires an ultrasound to get checked out with, not a CT scan, so the risks associated with that don't come into play here.
I agree that this is something you want to keep an eye on and should it get worse I always suggest going to the doctor.
