question: I am 41 yo. I have had 2 pe in less than a year. I have no factors that can dictate why. I am also not a smoker, never used birth control, and never had blood cflots in legs or arms. With the last blood clot I had a very high sensitivity to coumadin and ended up in the hospital 3 times getting a blood plasma fusion my hematlogist stated that the coumadin would kill me befor the clot. Three months later I find my self with another blood clot same lung back on coumadin. I am scared. Should I be concerned?
