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.
Hopefully Z-Pak will help and your back to normal soon. I'm not on any BP medicines so I can't speak to that but i'm sure a few peeps here can. I do know that Z-Pak didn't affect my INR at all.
Hang in there! You're almost done! And vent as much as you need to =)
