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.
That said, though, I would be concerned if I were you and was suddenly getting sun blisters. I hope you have mentioned it to your doc. It could be another med you are on or maybe a combo of that med and the warfarin.
Me, personally, I'm super-fair and burn like crazy anyway. Hats and 50 suncreen are my friends.
I am approaching the 50 y.o. mark in a few years and have been on Coumadin on and off since 1992 (low intensity since 2000). Never a problem with photosensitivity, and I spent a lot of time outdoors.
