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.

At first glance I didn't see mention of Lyme disease as a possible confounder. But that's to be expected from a site whose focus is APS---- and an excellent job they do too!
The sites I like best are ones that consider and discuss a topic from all points of view--- hence the post I made here: there will be very bias there because----- well, that's just how creative thinkers are. They can be a little irritating for some (grin) I understand.
"there will be very bias there because" = there will be very little personal bias there'
