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.
cmalt is so right, there's no such thing as normal. Everyone's experience with their recovery is different. It took me a LONG time to accept that. I'm still learning to let go of terms like "should" and "normal". Good luck with your breathing, and take care.
I'm hoping this year my lungs are more resiliant and I handle to changes better. I have to echo the idea of having a scarf over your nose and mouth. I wear a bandana outside when it is chilly now.
