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 mentioned above, what you are feeling are most likely superficial and not likely to put you at risk for a PE, though you should be concerned you are clotting elsewhere that could potentially pose problems.
If you're being treated for an infection and it's getting worse, you need to call your doc.
Let us know how you're doing.
