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.

my PE came out of no where.. husband and I drove to austin Tx about a 3 hr drive.. laughed the whole way down.. I get out of the car walk towards our destination, chest tightens, dizziness sets in, heart rate is like 10x the normal pace and sharp pains every time I breathed in.. everything went black.. Woke up on the ground to husband, security, and paramedics standing over me.. next thing I know we were code 3 on the way to Seton Medical center...
spent 2 1/2 days in ICU and 4 days reg room, 7 days total... Lets not count the number of ER visits I had after my PE only to have a nurse tell me it sounds like anxiety...
Glad to know it gets better.. Genetic testing will be next on my 2 do list...
