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.
After a CT scan,stones were seen in my gall bladder so PE was ruled out and Gall Bladder Attack was the prognosis.
The pain was localised to my right side at the bottom of my rib cage, the reason I was having problems breathing was that my gall bladder was swelled up and was pushing my liver into my lung.
I have been told by some who have experienced both(PE and Gall Bladder attacks) and they said that it is similar.
Hope this helps, not saying it's a gall stone or a gall bladder attack, heck people that know will tell you that I'm NOT a Dr, just talking from experience.
I'm still waiting for a date on the surgeon's table...
