'Hate to hear that, Butchna, and so sorry for your loss. You are correct on all counts. How do I know? I'm in stage 4 of CHF and in the transplant program at Duke University Hospital. My first PE was in '99. I literally died and was pronounced on a Life Flight copter in Austin before being shocked back and fighting for my life for several more hours. Since then, although on blood thinners (Warfarin for years...now Xarelto) I've managed to survive numerous DVTs and...truly and miraculously...survived multiple PEs in '13. I've literally flat-lined three times in total. Docs don't like to tell all their patients who're in this situation this, but recurrent clots are caused by more than just some propensity for having thin blood. A condition called antophospholipidautoimmune disorder (say that one fast three times) is usually at least part of the problem. I've had to restrict my activities somewhat and contact sports-like activities just aren't attempted. I ride my tried and true horses, but no more rock 'n rollin' on the bad boys. It sucks but just like any other avocations, football doesn't have to be the center of the universe. Sorry Trey. Life is long and you need to make the proper adjustments and keep living. Innovate, my good man, and turn this lemon into lemonade. God bless!
