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.
I can't imagine wearing them for 16 plus hours though. I want to be comfortable on on a long haul and compression stockings don't scream comfort to me, although mine are 30-40 thigh highs so that explains that.
I would think that absent swelling issues which I don't really get, we'd be less susceptible than the general public by the antocoagulation...
I've always been fine on shorter flights (2-3 hours), but that long-haul flight was killer. At this point, I have gotten more lackadaisical about it all, just because I do walk several times a trip, tap my feet, stay hydrated, am on anticoagulants, etc. The stockings are seeming less and less critical to me. I'd rather be comfortable and able to move around than assume they're providing some measure of help.
